Twelve Days Out: The Map Moved. Follow the Money.

On November 3, voters will decide two Congresses. The first is the 120th, which convenes in January. The results will determine who holds the gavels, which agenda moves, how hard Congress conducts oversight of the administration, and whether the last two years of this presidency bring unified government or divided government. The second is the Congress already in session. It returns after the election with a funding deadline and a stack of expiring authorities, and a majority that knows it is leaving bargains very differently from one that knows it is staying.

The topline

Republicans hold the Senate 53–47, so Democrats need a net gain of four seats. Here is where the forecasters and markets stand:

• Silver Bulletin: a 75% chance Democrats win the Senate and 94% for the House. In early September, Democratic Senate odds had fallen as low as 50%.
• Decision Desk HQ: Democrats at 57% to win the Senate, with a projected 51 seats.
• Sabato's Crystal Ball: 49 Senate seats at least leaning Democratic, 46 at least leaning Republican, and 5 Toss-ups.
• Cook Political Report: seven Senate Toss-ups, six of them held by Republicans.
• Kalshi: traders put Democrats at 67% for the Senate and 91% for the House.
• Polymarket: 91% for a Democratic House and 65% for a Democratic Senate as of October 19.

That is a big swing from earlier in the year. In March, Kalshi had Republicans favored 56–44 to keep the Senate. When VoteHub launched its forecast in May, it gave Republicans a narrow 51% chance of holding the chamber.

The House: a story told in numbers

In January, the House battleground was modest. Cook counted 36 competitive districts, compared with 49 at the same point in the 2018 wave. Democrats needed a net gain of just three seats.

The battleground has grown since then, and almost all of the growth is on Republican turf:

• Cook: 23 Republican-held seats are now rated Toss Up or worse for their party, compared with 11 Democratic-held seats. Cook's most likely outcome is a Democratic gain of 9 to 19 seats, and Democrats need only 20 percent of the Toss Ups to reach a majority.
• Sabato: On Tuesday it moved 28 House races toward Democrats in a single update. Democrats are now favored in 223 seats, so they could lose every Toss-up and still win the chamber.
• Polymarket: its seat projection shows 234 Democrats and 201 Republicans.

The map has also moved deep into red territory. Both parties are spending in about 60 districts that Trump carried by an average of roughly 8 points in 2024.

The Senate: from defense to offense

The year began with Democrats on defense. Cook's opening ratings listed only two Senate Toss-ups, Georgia and Michigan, both held by Democrats. Maine and North Carolina were Democrats' clearest pickup chances, followed by Ohio. Beyond those three, any path to a majority ran through seats Cook rated Solid Republican. To net four seats, Democrats needed to win in Trump country.

Today the picture is reversed.

Georgia and North Carolina are off the board. Cook rates both Ossoff's Georgia seat and the open North Carolina seat Likely Democratic. North Carolina is now a likely Democratic pickup: Silver Bulletin gave Roy Cooper a 95.3 percent chance of winning the seat Thom Tillis is leaving. Senate Leadership Fund had pledged $71 million to back Republican Michael Whatley, but it pulled most of its remaining ad reservations after spending about $32.8 million.

The core battleground is now held by Republicans:

• Maine. Troy Jackson, a former Maine Senate president, replaced Graham Platner as the Democratic nominee against Susan Collins. Kalshi traders price Jackson at 57% and Collins at 43%.
• Ohio. New Cook polling shows Sherrod Brown leading Sen. Jon Husted by 6 points.
• Texas. This is the most traded competitive race on Kalshi, where James Talarico leads Ken Paxton 68% to 33%.
• Iowa. It is the only Senate race Kalshi traders rate a pure toss-up.
• Alaska. Sabato moved Dan Sullivan's race to Leans Democratic.
• Kansas. Cook moved Roger Marshall's race from Lean Republican to Toss Up. Kansas has not elected a Democratic senator in 94 years.

Michigan is the one Democratic seat still in play. Cook still rates the open race between Mike Rogers and Abdul El-Sayed a Toss-up.

The second ring. Even Republican strongholds are drawing attention:

• South Carolina. Darline Graham was appointed to the seat after the death of her brother, Sen. Lindsey Graham, and won the nomination with Trump's endorsement. She faces pediatrician Annie Andrews.
• Mississippi. Cindy Hyde-Smith faces district attorney Scott Colom. Cook moved both the South Carolina and Mississippi races toward Democrats on Tuesday. Mississippi last elected a Democratic senator 44 years ago, and South Carolina 28 years ago.
• Nebraska. There is no Democrat on the ballot. Independent Dan Osborn is challenging Pete Ricketts, and public polling has been all over the map. A YouGov poll had Osborn ahead 48–47, while a Republican pollster had Ricketts up 46–43. Cook still rates the race Likely Republican, but at least one model calls it a toss-up and estimates an 11 percent chance that independents end up deciding Senate control. Trump rallied in Grand Island in early October.
• Florida. Forecasters still favor Republicans, but Ashley Moody leads Angie Nixon by about 6.5 points in the polling average, which is closer than Florida has been in years.
• South Dakota. A few forecasters, including Split Ticket and The Economist, have moved Mike Rounds's race from Safe to Likely Republican.

How to read horse-race news for the next twelve days

My advice: put less weight on the polls.

Polls convey less precision than people read into them. Take Cook's new Senate polls. Each surveyed 400 likely voters, with an expected error of about 4.9 points. That makes a 2-point lead in Iowa a coin flip with a headline attached.

Every poll you see was released for a reason. A campaign may want a close race to boost fundraising. A media outlet may cut corners on a cheap poll to get clicks. A campaign may push a rosy internal to keep donors believing. Sometimes it is worse: one pollster admitted to fabricating a Mississippi poll that showed Hyde-Smith up four points. Polls can also simply miss. In 2020, South Carolina polling showed a close Senate race, and Lindsey Graham won by 10 points.

Early vote numbers deserve even more skepticism. Silver has noted that Republicans make up a smaller share of early voters in several targeted states than they did four years ago. But who votes early is a habit, and habits change from cycle to cycle. Early ballots tell you who voted, not how they voted, so treat them as color rather than a forecast.

Instead, watch what the parties do with their two finite resources: money and candidate time. Party committees and leadership-aligned super PACs have their own private data and little reason to fool themselves. Every dollar and every hour they spend in one place is a dollar or an hour they cannot spend somewhere else.

Follow the money:

• Senate Leadership Fund is putting $5 million into South Carolina to help Graham in the final weeks.
• SLF is also spending about $1 million in Mississippi, responding to a $1.2 million ad buy from Senate Democrats' main super PAC.
• The Congressional Leadership Fund, Speaker Johnson's super PAC, stopped advertising for four Republican House incumbents.
• On the other side, the DCCC is now spending in 49 House districts, two-thirds of them held by Republicans, and just added three districts Trump carried easily.
• The DCCC also opened a $25 million line of credit, one of the largest it has ever taken out.

Republicans are cutting losses and spending to defend their own seats. Democrats are borrowing to push further onto Republican ground.

Follow the calendar:

• In October alone, Trump's rally schedule has taken him to Texas, Nebraska, Ohio, Alaska, Georgia, Kentucky, Kansas, North Carolina, South Carolina, Iowa and Florida.
• He will also rally in Corinth, Mississippi, eight days before the election, in a state he won by more than 22 points. A president does not spend his last week in Mississippi unless his team is worried about Mississippi.
• Speaker Johnson says he is visiting 40 congressional districts in 22 states this month. His second South Texas swing of the fall included districts the legislature redrew to favor Republicans. When the Speaker has to spend October protecting seats his party drew for itself, those seats are not yet won.

These signals aren't perfect. Spending can be offense as well as defense, and a rally can be a favor to a friend. But money and time cost something real, and a press-release poll costs very little.

What it means for the lame duck

Forecasts are not results. Sabato's Kyle Kondik notes that Democrats in 2020 and Republicans in 2022 both did worse than his outlet's forecasts. Whatever happens on November 3, the next few weeks in Washington will be shaped by four things.

We may not know the outcome for a while. California counts for weeks. Alaska is always slow. Maine's ranked-choice tabulation can add days to a close race. If House control comes down to a few late-counted seats, the outgoing Congress will be negotiating without knowing who controls the next one.

Storm clouds are gathering over the count itself. Democrats have sued to keep armed federal agents away from polling places, citing administration officials' statements that agents could appear there. Voting rights groups, unions and the city of Denver have filed similar suits. In July, the President used a prime-time address to revive unsupported claims of voter fraud and foreign meddling. Asked whether he would challenge the results, he told Time he doesn't rule anything out. Any effort to contest close results could complicate certification and the seating of the next Congress in January.

Republicans' working majorities could shrink before January.

• Senate. If Sherrod Brown wins, he does not wait until January. He is running in a special election for the remainder of JD Vance's term, so he would be sworn in once Ohio certifies the result, shrinking the Republican margin in the middle of the lame duck.
• House. The House majority is already razor-thin: 218 Republicans and one independent who caucuses with them, against 214 Democrats. Leadership has struggled all year to keep enough members in the building to pass party-line bills. If Democrats defeat a large number of incumbents, morale among members who have just lost their seats will make attendance worse. Republicans could effectively lose the ability to use their majority before the session ends.
• Democrats' incentives. Democrats would have little reason to help pass Republican-written bills when they are weeks away from writing their own.

The plate is full. We'll cover the agenda in more detail in a future piece, but the outline is clear.

The first wall comes on December 11, when both government funding and surface transportation authorities run out. A second set of deadlines follows at year's end:

• The Export-Import Bank's authorization.
• Expiring farm bill programs.
• A set of health care authorizations.

Then there is the annual National Defense Authorization Act, which Congress has passed every year for more than six decades. It could also become the vehicle to revive surveillance authorities that have already lapsed, along with other provisions.

Beyond the must-dos is a long wish list:

• A tax extenders package.
• Permitting reform.
• A full farm bill.
• The Water Resources Development Act.
• Hospital price transparency.
• Possibly the debt ceiling, and even another reconciliation bill.

The House is out until mid-November, which leaves roughly three working weeks before the first deadline and not much more before the second. The size of that list against that calendar is a better predictor of the lame duck than any poll.
