President Donald Trump announced plans on Oct. 19 to campaign in Kansas for Republican Sen. Roger Marshall, whose race against Democrat Adam Hamilton has produced narrow, conflicting poll leads ahead of the Nov. 3 election.
An event listing scheduled Trump's remarks for 7 p.m. ET (23:00 UTC) at Heartland Credit Union Arena in Park City. It named Trump 47 Committee, Inc. as the event's payer and said the rally was not authorized by a candidate or candidate's committee.
Trump said in an Oct. 19 Truth Social post that he was heading to Kansas to support Marshall. At a White House lunch, he had named Kansas as an upcoming campaign stop.
An InsiderAdvantage poll conducted Oct. 13-14 put Marshall at 48% and Hamilton at 47% among 1,200 likely voters. Its stated margin of error was 2.83 percentage points. An earlier YouGov survey, conducted Sept. 24-Oct. 4, put Hamilton at 48% and Marshall at 45% among 2,255 likely voters, with a 3.2-point margin of error. Neither lead exceeded its survey's stated margin of error.
Certified Kansas primary results show Marshall received 270,632 votes, or 79.90%, in the Aug. 4 Republican contest. Hamilton received 77,607 votes, or 34.63%, in an 11-candidate Democratic field.
Kansas last elected a Democratic senator in 1932, when George McGill won; he left office in 1939. In the 2024 presidential election, Trump received 57.16% of the state's vote, compared with 41.04% for Kamala Harris, according to official Kansas results.
Marshall has also faced scrutiny over medical debt cases. After reviewing Kansas court records, The New York Times reported that Marshall or his medical practice brought unpaid-bill lawsuits involving more than 700 patients. The newspaper said arrests occurred in 81 cases after patients missed court appearances. Trump defended Marshall in an Oct. 12 social media post.
Kansas voters will decide the Senate race in the Nov. 3 general election.
