Battleground 2026

Which House and Senate races decide control of Congress on November 3, and how likely each one is to be the decider. Built from ten forecasters' ratings, prediction markets, polls and FEC money. Updated 2026-10-31.

Senate
61%chance Democrats win control, from the forecasters' ratings
Polymarket: 72% · re-simulated on per-race market odds: 74%
Median outcome 51 D seats (80% range 48–55). Democrats need 51; 34 of their seats aren't up.
House
91%chance Democrats win control, from the forecasters' ratings
Polymarket: 94%
Median outcome 235 D seats (80% range 219–252); 218 needed. 181 seats are safe D and 111 safe R.
The short version. The Senate is leans Democratic (61% for Democrats). It turns on Alaska, Ohio (special election), Kansas, Texas and Maine, each between 9% and 10% likely to be the deciding seat. The House clearly favours Democrats (91%), and no single district matters much: the most pivotal is about a 2.1% chance of deciding it, because control depends on how dozens of races break together.

Could federal power be used to disrupt the midterms, through emergency powers, troops, or agents at polling places? This tab sets out what the law allows, what officials have actually said and done in 2026, and what prediction markets and election experts put on each scenario.

The short version. Federal law makes it a crime to send troops or armed agents to polling places, and no law lets a president postpone the election. DHS and the Joint Chiefs chairman say there are no plans to put ICE or troops at polls; the FBI director would not rule out sending agents. Prediction markets put a formal national emergency over election interference at 18% (Polymarket) by year-end, and the Insurrection Act being invoked for any reason at 14% (Polymarket) / 18% (Kalshi). The 31 experts Votebeat surveyed expect friction rather than a takeover: all 31 expect court challenges, 22 expect threats at polling places, and 26 say no result is likely to be overturned.

What the odds say

Prediction-market prices, fetched 2026-10-31. A price of 30% means traders collectively put about 3-in-10 odds on it. Markets can be thin and are not forecasts by experts.

Postponing or cancelling the election

What the law says

Congress sets the date of federal elections and states run them. No statute or emergency power lets a president postpone or cancel them.

Brennan Center: Trump can't use emergency powers to interfere with elections

What has happened

A national emergency over elections

What the law says

An emergency declaration unlocks about 140 specific powers in other laws, mostly over communications, transport and money. None covers elections, and the Constitution gives control of federal elections to states and Congress. The Supreme Court has limited or blocked Trump's use of emergency powers in tariff, National Guard and Alien Enemies Act cases.

Brennan Center · Center for American Progress

What has happened
  • Feb 26, 2026Press report The Washington Post reported pro-Trump activists, who said they were coordinating with the White House, were circulating a 17-page draft order declaring a national emergency over alleged Chinese interference in 2020. Trump said he had "never heard about it." source
  • Aug 11, 2026Remark Asked about declaring a national emergency to set voting rules, Trump declined to rule it out: "Stranger things have happened." source
  • Aug 31, 2026Action taken Renewed for another year the 2018 national emergency on foreign election interference (Executive Order 13848), as has been done every year since 2019. It authorizes sanctions on foreign actors who interfere in U.S. elections. It gives no power over how elections are run, though some pro-Trump sites described the renewal as a new election emergency. source
  • Sep 2026Press report The Atlantic reported some allies urging Trump to declare martial law; no such step has been taken. source

Troops or the Insurrection Act

What the law says

Since 1865 federal law (18 U.S.C. § 592) has made it a crime, punishable by up to five years, to send "troops or armed men" to a polling place, except to repel armed enemies of the United States. § 593 bars the military from interfering in elections. The Insurrection Act lets troops enforce the law, not break it.

Brennan Center: federal and state laws ban federal forces from polling places

What has happened
  • Aug 28, 2026Official statement Joint Chiefs Chairman Gen. Dan Caine to Sen. Elissa Slotkin: "The Joint Force has no plans to send Federal military personnel or Federalized members of the National Guard to polling places during the 2026 elections," nor to seize ballots or voting machines. He added he had "neither received nor anticipate[s] receiving any unlawful order" about the midterms. source
  • EarlierCourt The Supreme Court blocked the federalization of National Guard forces in Chicago. source

Markets: Insurrection Act invoked by Dec 31, 2026 (for any reason): 14% on Polymarket; Insurrection Act invoked before Jan 1, 2027 (for any reason): 18% on Kalshi; Martial law imposed in the US before Jan 1, 2027: 22% on Kalshi

ICE or other federal agents at polling places

What the law says

The same § 592 ban covers armed federal agents, and the person who orders them there is also liable. Voter intimidation is a federal crime (18 U.S.C. § 594) and voters can sue under the Voting Rights Act (52 U.S.C. § 10307). Agents may still respond to threats or serve warrants nearby.

What has happened
  • Feb 25, 2026Official statement DHS official Heather Honey told state election officials ICE will not be stationed at polling places. DHS: "ICE is not planning operations targeting polling locations." source
  • Mar 2026Action taken Bills to keep immigration enforcement away from polling places were offered in at least seven states (CA, CT, NM, PA, RI, VA, WA). Which ones passed is not confirmed here. source
  • May 2026Action taken San Antonio: ICE agents questioned a driver at a traffic stop near a polling place; local police asked them to leave. County officials said no voters were questioned and voting ran normally. source
  • Sep 15, 2026Official statement FBI Director Kash Patel declined to commit that FBI agents would stay away from polling places, saying agents would "follow the law" and that election-crimes coordinators sit in all 56 field offices. source
  • Sep 18, 2026Court Nine groups, including the NAACP, sued DHS and other agencies to bar agents from intimidating voters at polls. The government rejects the premise. Its Oct 28 declaration on who will staff poll monitors (see Justice Department poll monitors) was filed in this case; no ruling had been reported as of Oct 31. source
  • Oct 21, 2026Court Judge Araceli Martínez-Olguín restricted DHS's door-to-door "unlawful voting" operation, in which armed ICE agents questioned residents about whether they had voted and DHS posted videos of arrests, in nine states (CA, CT, GA, MO, NV, NY, PA, WA, WI) through Election Day. She found the target lists relied on unreliable data, some from "unknown artificial intelligence tools," and that the initiative likely amounts to voter intimidation under the Voting Rights Act. DHS: it is "laser focused on identifying, prosecuting, and removing aliens who vote." source
  • Oct 28, 2026Official statement In a sworn court declaration the Justice Department said no FBI or ICE personnel, and no one able to make an arrest, will serve as poll monitors. source
  • Oct 30, 2026Court The Ninth Circuit refused to pause the nine-state restrictions, finding the government had not shown irreparable harm, so they stay in force through Election Day.

  • EarlierRemark Steve Bannon, a former Trump adviser outside government, called for ICE to "surround the polls." source

Seizing ballots or voting machines

What the law says

States and counties own and control election materials. Federal agents can take them only with a court warrant; emergency economic powers do not reach American-owned property with no foreign interest.

What has happened
  • Dec 2020Press report A draft executive order to seize voting machines after the 2020 election was written but never issued. source
  • Jan 28, 2026Action taken The FBI executed a court-authorized search warrant at Fulton County, Georgia's elections hub and took roughly 650 to 700 boxes of 2020 ballots and records. Multiple 2020 reviews found no significant irregularities there. County officials called it "intimidation"; no charges had been reported as of Oct 31. source
  • May 6, 2026Court Judge J.P. Boulee ruled the Justice Department can keep the seized Fulton County materials, finding the seizure "certainly not perfect" but not unconstitutional. source
  • Aug 28, 2026Official statement Gen. Caine: the military has no plans to seize ballots, voting machines or other election material. source
  • Oct 30, 2026Court After DOJ letters to 57 of California's 58 counties threatened criminal investigations unless officials set aside ballots of alleged noncitizens within 48 hours, Judge Trina Thompson barred DOJ and DHS from threatening or coercing election officials to segregate ballots, purge voters or halt ballot processing. She also required the government to tell her of any search warrant applications or grand jury subpoenas for election materials tied to its lists. She wrote that the actions "are likely to have the effect of interfering with election administration and disenfranchising lawful voters." The order runs to Nov 16. source

Justice Department poll monitors

What the law says

Sending federal monitors is legal and routine: the Justice Department has done it in every election since the 1960s, under both parties. Monitors observe; they do not enforce. The question is scale and who staffs it.

  • Aug 2026Official statement Assistant AG Harmeet Dhillon said the department will send about 1,000 monitors in November, drawing volunteers from across the federal government. For comparison, the Biden Justice Department covered 64 jurisdictions in 2022 and 86 in 2024. source
  • Oct 22, 2026Action taken DOJ began notifying counties it plans to monitor, including Adams County (CO), Miami-Dade (FL), Hennepin and Ramsey (MN), King (WA) and seven Texas counties. Dhillon called it "the largest monitoring effort" in the department's history. Adams County's clerk called it "potentially an intimidation technique"; DOJ rejects that. source
  • Oct 28, 2026Official statement Sworn declaration by Voting Section acting chief Eric Neff: monitors will come from the Bureau of Prisons, ATF and DEA, not the FBI or ICE. They will be unarmed, wear no federal insignia, only observe and take notes, and not speak with voters inside polling places. source

Federal limits on mail voting

What the law says

The Constitution lets states and Congress set election rules. A federal judge has held that no law lets the Postal Service regulate election mail.

Votebeat

What has happened
  • Mar 2026Action taken Executive order: DHS builds state citizenship lists, the Postal Service delivers mail ballots only to listed voters, envelope design rules, and prosecution of officials who send ballots to ineligible people. The White House frames it as election security. source

How the odds are built

Ratings from ten forecasters (Cook, Sabato, Inside Elections, The Economist, Split Ticket, Decision Desk HQ, FiftyPlusOne, Fox, Silver Bulletin, RealClearPolitics), as compiled on Wikipedia and fetched 2026-10-31. Each rating is converted to a win probability (Safe .99, Likely .92, Lean .78, Tilt .62, Toss-up .50) and averaged across forecasters. Seats no forecaster rates as competitive are assigned by their 2026 partisan lean (Cook PVI), which accounts for mid-decade redistricting.

Simulation. 40,000 draws in which every race shares a national swing: any two races' outcomes are correlated at ρ = 0.25. Each race keeps its own average probability, but a good night for one party tends to be a good night everywhere.

"Chance it decides control." In each simulation, races are ordered from most to least Democratic. The one that delivers the 51st Senate seat (or 218th House seat) is the tipping point, and the column shows how often each race fills that role. This measures how pivotal a race is, not just how close it is.

Nebraska. Independent Dan Osborn has said he won't caucus with either party, so the model doesn't count his seat toward a Democratic majority. The ratings and markets shown for Nebraska are the odds that Osborn beats Republican Pete Ricketts.
