Democrats achieved significant gains in the Senate, flipping seats in both traditionally red and blue states, according to a Fox News Voter Poll. The "blue wave" was propelled by voter dissatisfaction with the economy, particularly inflation and gas prices, and a notable decline in President Donald Trump's approval ratings.
In South Carolina, Democrat Annie Andrews unseated Republican Darline Graham, a race that had been held by Graham's family for over two decades. Andrews found strong support among rural voters, independents, and women, while Graham struggled to retain key Republican voting blocs. The economy was the dominant issue, with over 40% of voters citing it as their top concern, and a majority blaming Trump's policies for economic hardships.
Ohio saw Democrat Sherrod Brown successfully defend his Senate seat against Republican Jon Husted. Husted's attempts to label Brown as "extreme" were largely ineffective, as voters perceived him as being too closely aligned with President Trump. Working-class and young voters, who had previously supported Trump, swung towards Brown. This demographic shift, along with a strong showing among Hispanic voters, contributed to Brown's victory.
Maine's five-term Republican Senator Susan Collins lost her seat to first-time candidate Troy Jackson. Democrats successfully linked Collins to President Trump, with a majority of Maine voters agreeing she was too supportive of the president. The state of democracy emerged as the primary issue for Maine voters, who overwhelmingly favored Jackson.
In Iowa, Republican Ashley Hinson was narrowly defeated by Democrat Josh Turek, flipping a seat in a state that had previously voted Republican. Concerns over tariffs, gas prices, and the war in Iran impacted rural voters, while Hinson's perceived closeness to Trump alienated other key demographics. Voters expressed significant dissatisfaction with the direction of the country and Trump's economic policies.
Kansas also saw a surprising flip as Democrat Adam Hamilton unseated Republican Senator Roger Marshall. Despite Marshall's campaigning with President Trump, his opponent capitalized on economic anxieties, including the price of gas and the impact of tariffs. A majority of Kansas voters felt Marshall was too supportive of Trump, and the president's own low approval ratings appeared to be a drag on Republican candidates.
Michigan's Senate seat remained in Democratic hands as Abdul El-Sayed defeated Republican Rep. Mike Rogers. El-Sayed successfully navigated accusations of extremism, while Rogers faced criticism for his strong ties to President Trump. Michigan voters expressed widespread disapproval of Trump's job performance and concern over the economy.
In Minnesota, Lt. Gov. Peggy Flanagan secured a victory for Democrats, holding retiring Senator Tina Smith's seat. While corruption was a concern for some voters, the state of democracy emerged as the top issue, heavily favoring Flanagan. Voters also expressed dissatisfaction with the economy and largely blamed Trump's policies for inflation.
Texas witnessed a significant upset as James Talarico defeated Ken Paxton, flipping a Senate seat in a traditionally Republican state. Talarico gained substantial support from Hispanic and young voters, groups that had previously leaned Republican. Paxton's controversial candidacy and the economic concerns of voters contributed to his defeat.
The Senate race in Alaska between Republican Dan Sullivan and Democrat Mary Peltola remained too close to call, with allegations of ballot manipulation casting a shadow over the election. Affordability and the state of democracy were key issues influencing voters.
The Fox News Voter Poll surveyed over 900 voters in South Carolina and Kansas, and thousands more in other states, between October 19 and November 3, 2026. The findings highlight a nationwide sentiment shaped by economic anxieties and a critical view of the incumbent president's performance.
