Trump's Rally Blitz Meets Limits in Senate Polls

President Donald Trump’s October campaign blitz coincided with narrower Democratic polling leads in Ohio and Texas, but the numbers don’t show a uniform Republican surge across the eight Senate races where he campaigned. Four races moved toward Republicans and four toward Democrats. No polling margin shifted by more than 2 points. The campaign machine traveled state to state, but it couldn’t command the map.

Small shifts, big campaign machinery

In Ohio, Democratic former Senator Sherrod Brown’s lead over Republican incumbent Jon Husted narrowed from 4.3 points to 3 points. Husted, the former lieutenant governor appointed to replace Vice President JD Vance, gained 1.3 points in the polling margin. Yet his displayed prices fell by 8.6 percentage points on Kalshi and 10 points on Polymarket.

In Texas, GOP Attorney General Ken Paxton cut Democrat James Talarico’s lead from 3.4 points to 2.5 points. Paxton’s displayed prices fell about 6 points on both prediction markets even as his polling margin improved. The numbers point in different directions, not to a tidy story of a rally-powered campaign.

Newsweek compared Silver Bulletin polling averages on October 1, the date of Trump’s first rally in each state, and October 28, the model’s latest update available at the time of writing. Trump’s October rallies also covered Alaska, Kansas, Iowa, Michigan, Georgia and North Carolina. Alaska, Iowa, Kansas, Michigan, Ohio and Texas were rated tossups by Cook Political Report.

Prediction-market prices aren’t projected vote shares. Newsweek recorded prices on October 1 and October 29, and noted that they change continuously to reflect traders’ assessments. Across all eight states, Republican candidates’ displayed prices fell in six states on at least one platform, with declines ranging from marginal to double-digit drops in Kansas and Ohio.

The candidates and the numbers

Kansas saw one of the larger movements. Republican Roger Marshall fell from 70.3 percent to 56 percent on Kalshi and from 72 percent to 56 percent on Polymarket, while Democrat Adam Hamilton’s polling position shifted from trailing by three-tenths of a point to leading by eight-tenths. Hamilton is the pastor of one of the country’s largest United Methodist congregations; Marshall practiced as an obstetrician for more than 25 years before entering Congress.

In Iowa, former television anchor and Republican Representative Ashley Hinson reduced Democrat Josh Turek’s edge from 1.6 points to 0.8 points. Turek is a state lawmaker who won two Paralympic gold medals in wheelchair basketball before entering politics. Hinson’s market price fell 6 points on Kalshi and 4 points on Polymarket.

Former FBI agent and House Intelligence Committee chairman Mike Rogers trimmed the Michigan margin held by public-health specialist and former Detroit health director Abdul El-Sayed by four-tenths of a point. Michigan market prices stayed broadly stable: Polymarket ended where it began, while Kalshi moved 1.8 points toward Rogers.

In Alaska, former congresswoman and tribal judge Mary Peltola expanded her lead over Dan Sullivan from 2.6 points to 3.6 points. Sullivan, a Marine Corps Reserve colonel and former state attorney general, gained 1.3 points on Kalshi and 2 points on Polymarket even as Peltola extended her polling advantage by 1 point.

Turnout is the pitch; causation remains unproven

Former Governor and Attorney General Roy Cooper added six-tenths to his substantial North Carolina lead over Michael Whatley. In Georgia, Senator Jon Ossoff widened his lead over Representative Mike Collins by 2 points. Ossoff and Cooper started above 93 percent on both prediction-market platforms, limiting the potential for further gains.

Newsweek said the polling shifts don’t establish that a rally helped or hurt a candidate. Advertising, fundraising, new surveys, early voting and other developments happened alongside Trump’s travel. The markets also incorporate polling, fundraising, advertising and early-voting information, so changing trader sentiment isn’t proof that Trump’s rallies caused Republican prices to fall.

Trump’s message to supporters included: “Pretend I am on the ballot.” He promised to campaign in roughly 35 competitive places and repeatedly urged voters to approach November as if his own political future were at stake. The coming election supplies the test, but the polling itself can’t isolate the effect of the president’s appearances.

Experts and Republican campaign officials told Newsweek that rallies may mobilize existing supporters more effectively than persuade undecided voters. “President Trump is the greatest force for turnout in American politics, and that’s why he is barnstorming the country and driving voters to the polls in the final stretch,” Natalie Baldassarre, the Republican National Committee’s national press secretary, said. Kyle Kondik, managing editor of Sabato’s Crystal Ball at the University of Virginia Center for Politics, said Trump’s influence as a campaigner was probably waning and individual appearances were difficult to isolate. “He has been very active on the trail, and I don’t know if you’re seeing a whole lot of poll movement,” Kondik said.

Costas Panagopoulos, a distinguished professor of political science at Northeastern University, said rallies were better suited to mobilizing committed partisans than converting undecided voters. “The evidence is mixed at best about the impact of Trump’s influence on the campaign trail in congressional races,” Panagopoulos told Newsweek. Election Day, November 3, will offer a clearer test of whether asking supporters to treat the midterms as Trump’s own contest helped Republicans overcome the historical penalty facing the party in power.
