On Tuesday evening, Donald Trump clearly won the White House. The rest of his group also did well; Republicans have retaken the Senate and appear to be on track to narrowly retain the House. They managed to defeat several of their most prominent Democratic targets, including Senators Sherrod Brown of Ohio and Jon Tester of Montana, and fended off challenges from incumbents in Texas and Florida as well as an unexpectedly strong bid from an independent candidate in Nebraska.

As of Thursday afternoon, the Senate's margin is 52-44 in favor of Republicans, with three outstanding races remaining, all in states Trump won: Arizona, Nevada and Pennsylvania. The results of these contests will determine the extent of the party's power in the upper house. The party currently has two moderate senators, Susan Collins and Lisa Murkowski, who have occasionally sided with their Democratic colleagues on certain issues or appointments. If the more conservative branch of the party can increase its numbers in the Senate, it could mean the difference between potentially quick or drawn-out confirmation hearings for Trump's future Cabinet members or Supreme Court justices. If Trump is impeached again, the Senate has sole power to convict and could likely override any Democratic support for his removal with a larger majority. The party's exact numbers in the House could also help determine who will control the Senate after the 2026 midterm elections, when Democrats will have few clear chances of gaining a lead.

With Democrats leading in two of the three yet-to-be-called elections, Republicans appeared poised to win a 53-47 majority in the Senate, an increase from the current balance of power in the chamber. Here's a look at the status of the remaining uncalled Senate elections.

In Arizona, Democratic congressman Ruben Gallego was running against Kari Lake, the conspiracy theory-friendly former news anchor and 2022 Republican gubernatorial candidate. As of Thursday morning, Gallego has a two-point lead in the open seat, by at least 50,000 votes, with 69 percent of those cast votes were cast. Politico points out that Gallego currently has the advantage and is likely to maintain his lead in the coming days. Polls on the race had often shown Gallego well ahead of Lake, with analysts leading the way Cook Political Report and Larry Sabatos Crystal ball Favoring the congressman in their ratings.

On Wednesday, Gallego said he and his team were “optimistic” about the results, while Lake urged her social media followers on Election Day to join Turning Point USA to help with election healing. “This race will be exciting until the end! We need ALL DEALERS ON DECK to heal the ballot and ensure every Arizonan’s vote counts,” she said.

Democratic Senator Jacky Rosen is seeking a second term and will face Republican former US Army Captain Sam Brown in Nevada. As of Thursday morning, Rosen leads Brown by almost 13,000 votes, which is less than one percent. Election experts say the remaining mail-in ballots will likely favor Rosen, which bodes well for her chances. Jon Ralston, the editor of Nevada Independent who is known for his in-depth knowledge of the country, got to the point on Thursday. “Rosen will win,” he said. Although the Associated Press has not yet decided the race, Decision Desk HQ is currently predicting a Rosen victory.

Early Wednesday morning, Rosen exuded confidence to her followers on social media. “We are happy with the results we are seeing, but there are still thousands of votes to be counted. Our democracy takes time and I am confident that as more votes come in we will win,” she wrote.

Bob Casey, the three-term Democratic senator, faced a tough re-election fight against Dave McCormick, a former hedge fund CEO who previously ran in the Republican primary for Pennsylvania's other Senate seat. McCormick currently leads Casey by about 30,000 votes, a difference of less than one percentage point. Although outstanding ballots still need to be counted, the path to a Casey victory appeared to be narrowing Thursday morning. Mark Davin Harris, a consultant for McCormick's campaign, said the majority of remaining ballots will come from Cambria County and favor McCormick.

In a statement released Thursday, the Casey campaign noted that the race is now within the threshold for an automatic recount in the state and maintained that it expects the senator will ultimately have the votes. The McCormick campaign later issued its own statement claiming victory based on the remaining ballots.

However, the Associated Press officially declared the race for McCormick on Thursday afternoon, making Casey the fourth Democratic seat to reverse this cycle.
