While the latest polls suggest Republicans are on course to regain control of the House of Representatives, nonpartisan analysts see the Senate as a “push” that is likely to come down to a handful of races in key states such as Pennsylvania, Georgia and Nevada . At the same time, Tuesday’s midterm elections are likely to throw the gun on the next US presidential election in 2024, with Biden and Trump considering another run for the White House. Biden has largely avoided the campaign trail for months amid persistently low approval ratings. But in the final stretch of the campaign, the incumbent has traveled the country to endorse a handful of congressional candidates and Democrats running for governor. On Saturday, Biden shared the stage with former President Barack Obama in Pennsylvania at a rally for John Fetterman, the Democratic Senate candidate there, and Josh Shapiro, who is running for governor in the state. On Sunday, he traveled to New York, where he campaigned with incumbent Democratic Gov. Kathy Hochsul, who faces an unexpectedly tough challenger in Republican Rep. Lee Zeldin. On Monday night, Biden will wrap up his campaign trip in another Democratic stronghold, Maryland, where polls show former investment banker Wes Moore as the likely front-runner to be elected governor. Speaking to Democratic supporters on a Zoom call Monday afternoon, Biden insisted he was “optimistic” about Tuesday’s election. “This is not a referendum, it’s a choice, and the more people we get out to vote, the more people we win,” Biden said. “So let’s go win.” Meanwhile, Trump has re-emerged on the political stage with a series of high-profile rallies alongside candidates he has endorsed in several key states, as well as in more traditional Republican strongholds. Recommended Over the weekend, Trump campaigned in Pennsylvania and Florida. On Monday night, he’ll share the stage in Ohio with JD Vance, the Hillbilly Elegy author who became the Republican nominee for US Senate there with Trump’s endorsement. Trump won Ohio by eight points over Biden in 2020, but the latest polls show Vance entering a much tighter race with his Democratic rival, Rep. Tim Ryan. Trump, 76, has been flirting for months with another run at the White House. At a campaign event in Iowa last week, he teased supporters, saying: “To make our country successful and safe and glorious, I will very, very, very likely do it again. . . very soon.” US media reported last week that Trump and his advisers were considering next Monday, November 14, as a possible official start date. Meanwhile, Biden, who will turn 80 later this month, has not officially said he will seek re-election in 2024. But Anita Dunn, a senior adviser to the president, said at an event in Washington last week that the initial discussions about the future campaign were underway.
