President Donald Trump canceled weekend rallies in Iowa and Kansas, where competitive Senate races could help decide who controls Congress, and replaced them with tele-rallies aimed at voters in nearly 20 states. Four days before the midterm elections, the campaign’s final push is shifting toward remote outreach—and the fight over control of the House and Senate.
The election will decide control of federal institutions, as candidates and party organizations compete to direct that power. Democrats led Republicans by 8.2 percentage points in RealClearPolling’s generic congressional ballot average, 51.4% to 43.2%. Prediction markets strongly favored Democrats to win the House, while the Senate contest remained closer.
A campaign managed from the top
The Republican National Committee said the tele-rallies would let Trump reach more voters during a final “72-hour sprint.” RNC Chairman Joe Gruters called the change “a huge boost in the closing days.” The shift came after Trump chose to skip in-person appearances in two states with Senate races that could affect control of the chamber.
Asked why he canceled the Kansas rally, Trump said, “I don’t feel like I have to go to Kansas,” and said Sen. Roger Marshall was “doing well.” Prediction markets still narrowly favored Republican Marshall in Kansas and Republican Ashley Hinson in Iowa. Current polling averages showed Democrats narrowly ahead in both states, making them among the contests that could help decide which party controls the Senate.
Markets offered another way to measure the contest. As of Friday morning, Polymarket gave Democrats a 94% chance of winning the House and a 69% chance of taking the Senate. Kalshi markets showed a similar outlook. Those prices aren’t polls or predictions of the final vote: they reflect what traders will pay for contracts tied to election outcomes, and can shift quickly. The figures reflect polling averages and market odds as of Friday, Oct. 30, 2026.
The limits of election-night certainty
Maine, Alaska, Ohio and Texas also remained important to the fight for Senate control. Poliwave tracked several extraordinarily tight Senate contests, but its report didn’t give specific results for those races. It said the map had tightened in unexpected places, with Iowa and Kansas potentially helping decide which party controls the Senate.
Trump campaigned across the country as Republicans tried to keep control of Congress. In Wisconsin, a Marquette Law School Poll released Oct. 28 found that 37% of registered voters approved of Trump’s job performance, while 61% disapproved. Trump sounded confident Thursday as he returned to the White House: “We’re going to have a strong Tuesday night.”
The 2026 midterm election takes place Tuesday, Nov. 3. Voters will decide control of the House and Senate, along with gubernatorial, state and local races across the country. Some House and Senate races could be called Tuesday night. Close contests may stay uncalled while officials count mail, provisional and other eligible ballots, so control of Congress may not be known that night.
The campaign’s public language centers on turnout, odds and control. The reported account identifies no grassroots organizing or mutual-aid response; it focuses on candidates, party officials, polling averages and traders’ prices. The institutions at stake are the same ones voters are being asked to choose between.
