The first Power Rankings of the 2026 midterm elections indicate a highly competitive contest between Republican Sen. Susan Collins of Maine and her likely Democratic challenger, Troy Jackson. The rankings suggest that the Maine Senate race is a toss-up, one of roughly a dozen key contests that will determine the balance of power in the Senate. The outcome of this election will be crucial in determining whether Democrats regain control of the chamber or Republicans maintain their slim majority.
A recent poll conducted over the past week shows Jackson with a slight three-point edge over Collins among likely general election voters in Maine. Jackson, a former Maine Senate president, is poised to secure the Democratic nomination at the party's convention, after winning the support of most of the state's voting delegates. His top rivals for the nomination have backed him, making his nomination all but certain.
Jackson's candidacy has gained momentum after the previous Democratic nominee, Graham Platner, dropped out of the race amid allegations of rape. Jackson has campaigned on a platform aimed at working-class voters, advocating for policies such as raising taxes on billionaires, implementing a universal healthcare system, and abolishing U.S. Immigration and Customs Enforcement. His progressive stance has earned him the support of prominent figures, including Sen. Bernie Sanders.
Meanwhile, Collins is facing a challenging re-election bid, with Republicans struggling to overcome President Donald Trump's low approval ratings, persistent inflation, and an unpopular war with Iran. Collins has been criticized by Democrats for her comments on Supreme Court Justice Brett Kavanaugh and her support for ICE funding. However, she has a history of defeating Democratic challengers, having won re-election by nearly 9 points six years ago.
The Senate race in Maine is one of several key battlegrounds that will determine the outcome of the midterm elections. Other toss-up contests include Senate races in Alaska, Iowa, and Ohio. Democrats need to gain a net of four seats to retake the majority, which they lost in the 2024 elections. The Maine Senate race is expected to be highly competitive, with both parties investing heavily in the campaign.
Collins' moderate reputation and ability to work across party lines have earned her bipartisan praise, including recognition for casting her 10,000th consecutive Senate vote. However, Democrats are targeting her over her past votes and statements, including her support for Justice Kavanaugh and ICE funding. The outcome of the Maine Senate race will have significant implications for the balance of power in the Senate and the future of the Republican Party.
