Democrat Adam Hamilton has pulled off a stunning upset in Kansas, becoming the first Democrat to win a Senate seat in the state since 1932 and ending a nearly century-long Republican streak.
Hamilton defeated Republican Senator Roger Marshall after a neck-and-neck battle that derailed the GOP's hopes of holding onto its Senate majority.
The Associated Press called the race for Hamilton at 11:25 pm.
President Donald Trump made a last-minute push to save Marshall's campaign, traveling to Salina, Kansas, on Sunday, just two days before Election Day.
Vice President JD Vance had also made two trips to the state to campaign for the incumbent senator.
Trump's visit came after a sudden U-turn following concerns over his decision to cancel a planned rally on October 29.
The RNC had insisted Republicans were in a strong position and that Trump would instead hold virtual events.
Trump also claimed Marshall was doing 'really well' and that he did not need to travel to Kansas.
However, he reversed course a day later and reinstated the rally as the race as he didn't like the optics around the cancellation.
In a stunning upset, Democrat Adam Hamilton won by over 100,000 votes

The Republican campaign arm had poured millions into trying to save Marshall from embarrassment.
After the August primary, Republican groups committed more than $26 million in advertising to boost his campaign, more than they spent during his entire 2020 race.
It was a rescue mission after some Republican operatives believed Marshall took his campaign for granted.
Hamilton and Democratic groups committed more than $38 million, bringing total advertising spending in the state to around $71 million and setting a record for Kansas.
Marshall's campaign repeatedly attacked Hamilton as 'too woke and too weak for Kansas,' while a Senate Leadership Fund advertisement described him as a 'two-faced' extremist.
The Republican also aired an advertisement criticizing how Hamilton's church handled abuse at youth camps in 2005 and 2006.
Hamilton said the incidents were reported to police and that he personally helped ensure the abuser was convicted.
Hamilton, meanwhile, aired an advertisement featuring a woman who said she was arrested over Marshall's medical-debt collection practices when he worked as a doctor in western Kansas.
Marshall's lawyers sent a cease-and-desist letter, which Hamilton dismissed as ridiculous.
The Democratic challenger, a prominent Methodist pastor, focused much of his campaign on economic frustration, particularly rising fuel and fertilizer prices that have squeezed farmers across Kansas.
He also attracted support from independent voters and some moderate Republicans, helping make the contest far more competitive than expected.
Marshall, who has represented Kansas in the Senate since 2021, campaigned on continuing Trump's agenda and warned that a Democratic victory could hand control of the chamber to the opposition.
Trump carried Kansas by more than 16 points in 2024, making Hamilton's victory a major upset in a state that has traditionally been a reliable Republican stronghold.
In a last-minute attempt to defend his record, Marshall released a campaign video explaining why his former medical practice pursued patients over unpaid medical bills.
Marshall said his office frequently provided free care but occasionally turned unpaid accounts over to collection agencies to keep the practice running.
However, the video was reportedly filmed and released without the knowledge of some of his senior campaign advisers, who had urged him not to revisit the controversy so close to Election Day.
Marshall later said voters had repeatedly asked him about the issue and that he wanted to explain his side.
The senator's victory comes after the race tightened dramatically in the final weeks, turning what is usually a safe Republican seat into one of the country's most closely watched contests.
Trump carried Kansas by more than 16 points in 2024, but Hamilton's centrist campaign and voter concerns about the economy helped make the race more competitive than expected.

Marshall, who has represented Kansas in the Senate since 2021, campaigned on continuing Trump's agenda and warned that a Democratic victory could hand control of the chamber to the opposition.
Kansas has not elected a Democrat to the Senate since 1932, making the close contest an unusual test of Republican strength in a state Trump won comfortably.
