Democrat leads Marshall in tight Kansas Senate race: Poll

Hamilton Holds Narrow Edge in Kansas Senate Survey

Provpnadvice.com – Kansas Democrats may have an opening in a race that has long been dominated by Republicans. A new survey of likely voters places Democrat Adam Hamilton slightly ahead of Republican Sen. Roger Marshall, 45 percent to 43 percent, in the contest for a U.S. Senate seat.

The two-point margin remains within the survey’s credibility interval, meaning the race is still highly competitive. Libertarian candidate David Graham received 4 percent support, while 8 percent of likely voters said they had not yet made a decision.

For Hamilton, the senior pastor of the Church of the Resurrection, the campaign represents an opportunity to achieve a result Kansas Democrats have not managed in nearly a century. The last Democrat to win a Kansas Senate election was former Sen. George McGill in 1932. Marshall, meanwhile, is seeking a second term after winning the seat by a double-digit margin in 2020.

Independent Voters Could Shape the Result

The survey suggests Hamilton’s strongest advantage may be among independents. Spencer Kimball, executive director of Emerson College Polling, said Hamilton leads Marshall by 15 points with that bloc of voters.

“This poll finds Democrats with their best chance to win their first Senate seat in Kansas since 1932, in part driven by Democrat Hamilton’s appeal to independent voters, leading by 15 points,” said Spencer Kimball, executive director of Emerson College Polling.

That finding is especially notable in Kansas, where statewide federal races have historically favored Republicans. A close Senate contest does not guarantee a Democratic breakthrough, but it indicates that unaffiliated voters may be more willing to consider a candidate outside the state’s usual partisan alignment.

The large share of undecided respondents also leaves room for change. With 8 percent of voters still uncommitted, both campaigns have a meaningful group to persuade in the remaining stretch. In a contest separated by only two points, turnout operations, advertising, candidate appearances and late-breaking events could all influence the final result.

Race Ratings Move Toward Democrats

Election analysts have taken notice of Hamilton’s campaign. Cook Political Report moved its rating for the Senate contest from “solid” Republican to “likely” Republican last month. The shift followed Hamilton’s primary victory and reflected a stronger-than-usual opportunity for Democrats seeking to end Kansas’s long Senate-election drought.

Decision Desk HQ also continues to view the contest as likely Republican, underscoring the difference between a favorable poll and a broader forecast. Kansas remains a difficult statewide environment for Democratic candidates, and Marshall begins with the advantages of incumbency and a recent decisive victory.

Still, the race has drawn attention beyond the normal expectations for a Kansas Senate campaign. Former Republican Gov. Bill Graves endorsed Hamilton this week, framing the choice as a response to political division and legislative deadlock.

“[The country is] facing increasing partisan gridlock and division” and it is “time Kansas does something different,” Graves said.

Graves’s support gives Hamilton a prominent Republican voice in his coalition. Such endorsements do not automatically translate into votes, but they can reinforce an argument aimed at independents and Republican voters who are dissatisfied with the direction of national politics.

Libertarian Candidate Adds Another Variable

Graham’s presence on the ballot could become important in a close contest. His 4 percent share is larger than the current gap between Hamilton and Marshall, making third-party voters a potentially decisive factor if their preferences shift before Election Day.

Kimball said the Libertarian campaign is affecting the Senate race differently than the race for governor. Graham’s supporters appear to have a distinct role in the Senate contest, while Libertarian-leaning voters in the gubernatorial election break more heavily toward the Republican nominee.

“Graham’s third-party candidacy shakes up the Senate race in a way we do not see in the governor’s contest,” Kimball said.

Third-party candidates often complicate efforts to read a head-to-head matchup. Some voters may be firmly committed to their choice, while others may move to one of the major-party candidates as the election approaches. For Marshall, consolidating right-leaning voters could be central to his path. For Hamilton, maintaining his independent-voter advantage while limiting Republican consolidation would be equally important.

Governor’s Contest Favors Republicans

The same survey found a different picture in the Kansas governor’s race. Republican Ty Masterson, president of the state Senate and backed by President Trump, led Democratic state Sen. Cindy Holscher 51 percent to 44 percent. Holscher has the backing of term-limited Democratic Gov. Laura Kelly, and 6 percent of respondents remained undecided.

Independent voters were closely divided in that contest, but Masterson held a narrow edge among them, 47 percent to 45 percent. Both Cook Political Report and Decision Desk HQ rate the governor’s race as leaning Republican.

The split results offer a reminder that Kansas voters may evaluate statewide candidates individually rather than supporting one party across every race. Voters can choose different parties for Senate and governor, particularly when candidate backgrounds, campaign messages and local concerns differ.

Kansas backed Trump in each of his three presidential campaigns, and Vice President Vance visited the state this week to promote Republican candidates. That political backdrop remains a major challenge for Democrats. Yet Hamilton’s position in the survey suggests the Senate race could be more competitive than recent Kansas history would normally suggest.

The poll was conducted Sept. 15 and 16 among 750 likely voters. Its credibility interval was plus or minus 3.6 percentage points, placing the current Senate margin well inside the range where a small change in voter sentiment could alter the apparent leader.
