Midterm Preview: What to Watch on Nov. 3 — and What Comes Next….
Four days to go. If your phone has received more campaign texts this month than texts from people you actually know, you’re in good company. Here’s a field guide to what happens next Tuesday, and why the weeks after it may matter even more.
The short version
Election Day is Tuesday, Nov. 3. Here’s what the people who forecast this for a living expect:
Democrats are very likely to win the House. Forecasters give them roughly an 80–95% chance. They need to gain only about 4 seats; most projections show them gaining 12–22.
The Senate is a real nail-biter. Democrats need to gain 4 seats there too, and their odds sit around 55–75%. A handful of races — Maine, Texas, Ohio, Iowa, Kansas — will likely decide it, possibly well past your bedtime.
The national mood favors Democrats. Asked which party they want running Congress, voters prefer Democrats by about 8–9 points. The President’s approval rating is about 36%.
Expect a lot of new faces. At least 72 House seats will have a new member no matter who wins, one of the biggest turnovers in a decade. That’s a rare chance to build relationships early (more on that at the end).
Terms & What they Mean….
Toss-up - Either side could win. Forecaster for “honestly, flip a coin”
Lean / Likely - One side has a small edge / a clear edge
Generic ballot - A poll question: “Which party do you want controlling Congress?”
Wave -An election where one party wins far more seats than usual. Pundits love this word
Open seat - No incumbent is running
Flip - A seat that changes parties
Who the forecasters are: Cook Political Report rates races based on reporting and a lot of phone calls; Decision Desk HQ and Silver Bulletin run statistical models; Kalshi and Polymarket are betting markets where people put real money where their mouths are.
How likely is each outcome?
A word of caution on this year’s polls. Take every number here with a little extra salt. In October, a firm called Wedgewood Polls admitted it had made up most of its surveys, and reporters flagged at least two other questionable outfits. Several poll trackers and forecasters, Silver Bulletin, The New York Times, FiftyPlusOne and Decision Desk HQ among them, had included Wedgewood’s numbers before pulling them out. Removing them nudged things slightly toward Republicans (in Silver Bulletin’s average, Democrats’ share of the generic ballot slipped about two-tenths of a point), and the model forecasts in this newsletter come from after those removals.
On top of that, ordinary polling error is real: polls missed by about 2.5 points in 2024, and they missed in the opposite direction in the 2022 midterms. A miss of 2–3 points in either direction could flip several of the coin-flip races below. So read these odds as a range, not a promise — the confetti may land somewhere else.
Think of these like a weather forecast: a 75% chance of rain still means one day in four you leave the umbrella at home and stay dry. Pollsters have been humbled before, so hold the numbers loosely.
_________________________________________________________________________________________
I predict Democrats will win 25 seats in the House and 6 seats in the Senate, more than enough to flip control of both chambers in Congress. The president’s erratic economic trade war and war of choice in Iran have increased the price of gasoline, diesel, food, and clothing and even his most loyal supporters know it and can feel it. Trump’s approval rating is lower today than it was in the days following the January 6 insurrection and 70% of Americans think the country is headed in the wrong direction. Trump’s historic 2024 coalition that included higher than usual support from Hispanics and young men of all races has imploded over broken promises to “stop endless wars, lower prices, release the Epstein Files, and drain the swamp.”
While polls don’t predict winners, they can show trend lines and momentum. Everything has pointed “blue” since Labor Day and it is too late for Republicans to reverse course — nearly half of all ballots in the 2026 midterms have already been cast. This is baked.
You’ll hear from Republican insiders that you “shouldn’t trust the polls” and many Democrats will agree— largely due to scar tissue from 2016 & 2024 when polls underestimated MAGA turnout in swing states. I don’t buy this argument in 2026. Why? Because when Trump isn’t on the ballot, the polls have been spot on over the last decade. In 2017, 2018, 2019, 2021, 2022, 2023 & 2025 off-year elections, polls actually underrepresented shifts towards Democrats. Every time Trump isn’t on the ballot, Republicans have a bad night.

The Senate: seven races to watch
Republicans control the Senate 53–47. Democrats need to gain 4 seats to take over, because the Vice President breaks 50–50 ties for Republicans (the rare job that is mostly waiting around for a tie). Democrats are favored to pick up North Carolina, so the real question is whether they can win 3 of these 7 close races:
Who’s running & How close are the races?
Maine - Sen. Susan Collins (R) vs. Troy Jackson (D) / Coin flip; Jackson up about 2 in polls
Texas - Ken Paxton (R) vs. James Talarico (D) / Coin flip; Talarico up about 2
Ohio - Sen. Jon Husted (R) vs. Sherrod Brown (D) / Coin flip; Brown up about 3–4
Michigan - Mike Rogers (R) vs. Abdul El-Sayed (D) / Coin flip; El-Sayed up about 3. Democrats must hold this one
Alaska - Sen. Dan Sullivan (R) vs. Mary Peltola (D) / Coin flip; Peltola up about 3
Iowa - Ashley Hinson (R) vs. Josh Turek (D) / Dead even
Kansas - Sen. Roger Marshall (R) vs. Adam Hamilton (D) / Dead even
Seven coin flips, and Democrats need to call three of them right. Anyone who tells you they know exactly how this ends is selling something!
Two to keep an eye on:
Texas — Democrats haven’t won a Senate race there since 1988, the year Die Hard came out. A win would signal a very big night.
Nebraska — independent Dan Osborn is running close against Sen. Pete Ricketts and hasn’t said which party he would side with. If the Senate ends up near 50–50, the most powerful person in Washington could be a former mechanic from Omaha.
The House: not whether, but how big
Republicans hold the House 219–214. Democrats need a net gain of about 4 seats. Cook Political Report now expects them to gain 12–22, which would give them roughly 227–237 of the 435 seats. At this point the House is less a horse race and more a question of how many horses cross the line.
The size of the win matters. A slim majority means every vote is a negotiation (picture herding cats, if the cats each had a press secretary). A large one gives leaders room to act. On election night, watch three groups of races:
The true toss-ups (17 races). Examples: Rep. Brian Fitzpatrick’s suburban Philadelphia seat, Rep. Mike Lawler’s seat north of New York City, and open seats in Iowa, Maine and Kentucky. If Democrats win most of these, they’re on track for a solid majority.
Republican seats now tilting Democratic. Six districts President Trump won, including those of Reps. Juan Ciscomani (Arizona), Gabe Evans (Colorado), Jen Kiggans (Virginia) and Derrick Van Orden (Wisconsin). A sweep here points to a big gain.
Long shots that would signal a wave. Rep. Lauren Boebert (Colorado), Rep. Eli Crane (Arizona), Rep. John McGuire (Virgina), Alaska’s statewide seat, and districts in Ohio, Kansas, South Carolina and Nebraska.
If several of these fall, Democrats could gain 25 seats or more — and cable news will run out of synonyms for “wave.”
Governors and the states
Congress gets the headlines, but governors decide a lot of what actually shows up in your life — from how Medicaid works to how fast the pothole on your street gets fixed. 36 states elect governors this year, and 15 of those races have no incumbent because of term limits. Republicans hold 26 of the 50 governorships today; Democrats could win a majority for the first time since 2010. The four closest:
Who’s running & How close are races?
Georgia - Rick Jackson (R) vs. Keisha Lance Bottoms (D) / Tied
Nevada - Gov. Joe Lombardo (R) vs. Aaron Ford (D) / Coin flip
Maine - Bobby Charles (R) vs. Hannah Pingree (D) vs. Rick Bennett (I) / Suddenly close: Pingree led by about 11 in earlier polls, but the newest poll (Marist) shows a 44–44 tie
Wisconsin - Tom Tiffany (R) vs. David Crowley (D) / Slight Democratic edge
Ohio- Vivek Ramaswamy (R) vs. Amy Acton (D) / Slight Democratic edge
Michigan - John James (R) vs. Jocelyn Benson (D) / Benson up about 6–12 in recent polls
Why governors matter: they decide how federal programs like Medicaid and infrastructure money are spent in their states. A new governor also brings in new agency heads and senior staff, a whole new set of people to get to know.
Also on the ballot: voters in 39 states will decide ballot questions, mostly about taxes (such as a proposed billionaire tax in California and phasing out the income tax in Missouri), plus housing, voting rules and more. Several state legislatures could also change hands, including in Michigan, Pennsylvania, Wisconsin, Arizona and Minnesota.
Three ways election night could go
Pick your own adventure — except you don’t get to pick, and the ending arrives sometime after midnight.
If it’s…
A modest wave (most likely)
About 2 in 5
Democrats gain 10–20 House seats; Senate lands near 50–51
Narrow majorities. Every vote is negotiated, and small groups of members gain real leverage
A big wave
About 1 in 3
Democrats gain 20+ House seats and reach 52–54 senators
Democrats run both chambers with room to spare: more investigations of the administration, and Democrats decide which judges and cabinet nominees are confirmed
A split Congress
About 1 in 4
Democrats win the House narrowly; Republicans keep the Senate
Gridlock on most bills. The House investigates; the Senate keeps confirming the President’s nominees
Republicans keeping both chambers is possible but unlikely; roughly 1 in 10, depending on the source. Unlikely things do happen; ask anyone who has filled out a March Madness bracket.
Signs to watch on election night: if Democrats win the Senate races in Ohio and Maine, a big night is likely. If Reps. Fitzpatrick and Lawler hold their seats, expect a more modest result. Politico reports that private polling shows the race tightening in the Midwest, so a modest wave is a sensible expectation. Pace yourself on the snacks.
Either way, if the House changes hands, every committee gets a new chair and new senior staff in January, which is where things get interesting.
_________________________________________________________________________________
With just days remaining until the midterms, the usual cascade of confident polling stories has largely vanished. Even the New York Times’ rare contribution is a cautious op-ed of “best guesses” that asks whether a blue wave is coming at all, not how large it might be. The pollsters themselves are hedging hard: they describe the numbers as offering perspective rather than prophecy, concede they may be slightly too optimistic for Democrats, and openly admit they could be wrong again -- especially in the Midwest, where past overestimates of Democratic support have occurred. The recent collapse of several dubious or fake polling firms has only deepened the skepticism.
Because the accuracy of polling firms seems to have gotten worse rather than better, I don’t believe the outcome can be forecasted with confidence. This is no ordinary midterm, so turnout alone will decide the outcome.

Committees to watch: who takes over, and what changes
If Congress is a restaurant, the floor votes are where the plates come out, but committees are the kitchen. That’s where bills get written, hearings get held and investigations get cooked up, and the party in charge picks every head chef. Because the House is very likely to flip, the House changes below are close to certain. The Senate changes happen only if Democrats win the Senate (about a 55–75% chance).
The committees that will feel the biggest shift are the ones that investigate: Oversight, Judiciary and Financial Services in the House. Here’s how the three you’re tracking line up:
Committees: Current Chair, Likely Chair if Chamber flips…
House Oversight - Current Chair, Rep. James Comer (R-Ky.) / Likely Chair in January, Rep. Robert Garcia (D-Calif.)
Almost anything: federal agencies, the White House, government spending
House Financial Services - Current Chair, Rep. French Hill (R-Ark.) / Likely Chair Rep. Maxine Waters (D-Calif.), facing a possible challenge.
Banks, the Federal Reserve, crypto, housing, insurance
Senate Banking - Current Chair, Sen. Tim Scott (R-S.C.) / Likely Chair, Sen. Elizabeth Warren (D-Mass.)
Banks, the SEC, housing, export controls
House Judiciary - Current Chair, Rep. Jim Jordan (R-Ohio) / Likely Chair, Rep. Jamie Raskin (D-Md.)
Justice Department, courts, immigration, antitrust
Senate Judiciary - Current Chair, Sen. Chuck Grassley (R-Iowa) / Likely ChairSen. Sheldon Whitehouse (D-R.I.), since Sen. Durbin is retiring
Confirming federal judges, Justice Department, immigration, antitrust
House Energy and Commerce - Current Chair, Rep. Brett Guthrie (R-Ky.) / Likely Chair, Rep. Frank Pallone (D-N.J.)
Health care, tech and privacy, energy, consumer protection
Senate Commerce - Current Chair, Sen. Ted Cruz (R-Texas) / Likely Chair, Sen. Maria Cantwell (D-Wash.)
AI and tech, telecom, transportation
Oversight: the one to watch.
House Oversight can investigate pretty much anything it wants, and its seats tend to go to the most outspoken members of each party.
Whichever party runs it uses it to keep the other side’s administration on the defensive; after Republicans took the House in 2023, they used it to dig into the Biden family.
Under Garcia, expect subpoenas for current and former administration officials (he has named Stephen Miller, Kristi Noem and Corey Lewandowski), a continued Epstein investigation, and probes into Trump family business dealings, immigration enforcement and corporate pricing.
Garcia says impeachment isn’t at the top of his list. Either way, it should make for two long years of hearings, and good TV for C-SPAN fans.
Financial services: more scrutiny, slower crypto.
Expect hearings with bank and tech CEOs and close questioning of regulators who have eased oversight. Waters and Warren have both focused on housing costs and consumer protection.
The major crypto bill (the CLARITY Act) is unlikely to move in its current form under a Chair Warren. A Democratic sweep would put crypto skeptics in charge of every committee that handles it.
Warren has worked with Republican China hawks on limiting exports of advanced AI chips, an area where a Banking chair has real power.
Watch the House leadership fight: Rep. Sean Casten (D-Ill.) plans to challenge Waters, 88, and Rep. Bill Foster (D-Ill.) may run too. Most committee Democrats have endorsed Waters.
Judiciary: investigations, and the fight over judges.
Raskin has promised “aggressive” oversight of the Justice Department, presidential pardons and alleged pay-to-play dealings. House Judiciary and Oversight are already splitting up the work.
The Senate is where the biggest change would be felt: a Democratic Senate decides which of the President’s judges are confirmed. Several Democrats have said they would not confirm a Supreme Court nominee if a seat opened.
Whitehouse has said the Supreme Court itself would be an early focus for oversight.
Commerce: AI rules move to the front.
Cantwell has released a six-point AI safety plan (federal safety standards, ongoing testing, independent audits). That is a sharp turn from Cruz’s push to block state AI laws without a national framework.
House Democrats’ first-100-days plan includes drafting AI rules and banning stock trading by lawmakers. Pallone’s committee would lead on health costs, privacy and consumer protection.
Expect a renewed push on a national privacy law, which Cantwell has championed before.
If only the House flips: House committees can investigate, subpoena and hold hearings, but new laws still need the Senate. Scott, Grassley and Cruz keep their gavels, and the President’s nominees keep moving. Translation: lots of hearings, fewer bill signings.
The opportunity: dozens of brand-new offices
Here’s the part that matters no matter who wins: Washington is about to get one of its largest groups of newcomers in a decade. It’s the first day of school, and nobody knows where the cafeteria is yet.
At least 72 new House members, guaranteed: 61 members chose not to run again and 11 lost their primaries. Seats that flip could push the total to 80–95.
A double-digit group of new senators is possible.
At least 15 new governors, each bringing new agency heads and senior staff.
New committee leaders if the House changes hands — every chair and their top staff change over.
Why act now: new members arrive with a campaign team, a lot of enthusiasm and, often, no idea where the bathrooms are in their new building. Most of their senior staff are hired in the eight weeks between Election Day and the Jan. 3 swearing-in. The people who show up early with something genuinely useful become the people they call later. Be the one who brings the map.
What to do:
First week of November
Results come in; close races are still being counted
Send a short congratulations note. No asks yet — let them enjoy the confetti
Mid-November
New members come to Washington for orientation
Find out who is leading each new team; offer a one-page primer on your issue and how it affects their district
December
New offices hire staff and request committee assignments
Suggest strong staff candidates if asked; share data that helps them make their case for a committee
January
Members are sworn in; offices open
Request introductory meetings with policy staff; invite them to visit your local sites
February–March
First hearings and budget requests
Be their go-to source before the first big decisions
Who to focus on: new members joining the committees that handle your issues, and new members from states where you have people or facilities.
Keep it clean: lead with information, not asks. Ethics and gift rules apply once members are sworn in, and transition staffers cannot be lobbyists. A good one-pager beats a fancy dinner every time anyway.
_____________________________________________________________________________________
History demonstrates that when control of Congress changes in a midterm election, especially in a president's second term, the new majority in Congress spends as much time preparing the first draft of the policy agenda for the next president’s term as they do governing with the incumbent president. It is critical to start the preparation work for 2029 in 2027 because many of the next president’s policy priorities will be written long before January 20, 2029.
Thanks for reading. Vote if you haven’t, hydrate, and we’ll see you on the other side of Tuesday.
