President Donald Trump's monthlong campaign tour produced a split verdict across eight Senate races, and Iowa sits near the center of the story. Republican Representative Ashley Hinson cut Democrat Josh Turek's lead in the state's Senate race from 1.6 points to 0.8 points during October, according to a Newsweek analysis published October 30.
The review covered Senate contests in Texas, Ohio, Alaska, Kansas, Iowa, Michigan, Georgia and North Carolina, all stops on Trump's nearly daily rally schedule. Six of the eight are rated tossups by the Cook Political Report, meaning they could decide control of the Senate on November 3.
What the Polling Shows in Iowa
Hinson, a former television anchor making the jump from the House to a Senate bid, gained ground even as traders on prediction markets grew less confident in her chances. Newsweek compared Silver Bulletin polling averages on October 1, the date of Trump's first rally in each state, and October 28. Across the full period, four races moved toward Republicans and four toward Democrats, with no margin shifting by more than 2 points.
Turek, a state lawmaker who won two Paralympic gold medals in wheelchair basketball before entering politics, held the slimmest Democratic edge of any race in the analysis. His 0.8 point lead makes Iowa one of the closest Senate contests in the country heading into the final days.
Why Prediction Markets Tell a Different Story
While Hinson gained in the polls, her displayed price on Kalshi fell by 6 points and on Polymarket by 4 points. The same divergence appeared in Texas and Ohio, where Republicans gained modestly in polling margins but traders became less confident.
Prediction market prices change continuously and reflect traders' assessments rather than projected vote shares. They incorporate polling, fundraising, advertising and early voting data, so their movement shows shifting sentiment rather than proof that Trump's rallies hurt any candidate.
Trump's Message: Pretend I Am on the Ballot
From airport hangars in Alaska to arenas in states Republicans once expected to hold comfortably, Trump has carried a consistent message:
