Ten Senate Races Will Decide Congressional Control on Election Day
Voters in states from Alaska to Texas are deciding the fate of the Senate, with Democrats needing a net gain of four seats to reclaim the chamber.

Polls are open across the United States as voters head to the ballot for the 2026 midterm elections, which will determine the balance of power in Congress for the final two years of President Donald Trump's second term. The Associated Press describes the contest as a referendum on the administration, with many citizens expressing frustration over high prices and an unpopular war with Iran. More than 57 million people had already cast ballots by Monday, surpassing early voting totals from four years ago in many closely watched states.
The outcome of these races will dictate which party controls the Senate, where Democrats currently hold 45 seats against 53 for Republicans. To secure a majority, Democrats need a net gain of four seats, while Republicans can afford to lose only two. The Associated Press notes that one or two seats could tip either chamber, making the specific matchups in ten states particularly critical to the final tally.
In North Carolina, Democratic former Governor Roy Cooper is challenging former Republican National Committee chair Michael Whatley for the seat vacated by retiring Senator Thom Tillis. The Associated Press notes that Tillis stepped down after clashing with the president, and the state voted for Trump by 3.3 points in 2024. Meanwhile, in Georgia, incumbent Senator Jon Ossoff is defending his seat against Republican Representative Mike Collins. Race ratings suggest Georgia is leaning or likely Democratic, though Trump won the state by 2.2 points in the previous cycle.
The race in Ohio features Democratic former Senator Sherrod Brown against Republican Senator Jon Husted, who is running in a special election to finish the term elected by JD Vance. In Michigan, Democratic candidate Abdul El-Sayed is facing Republican former Representative Mike Rogers in an open seat race. The Associated Press reported that El-Sayed's former primary opponent, Haley Stevens, endorsed Rogers on Sunday, adding a dynamic element to a state that voted for Trump by 1.4 points.
Texas presents a high-profile contest where Republican Attorney General Ken Paxton, who received Trump's endorsement over Senator John Cornyn in the primary, is running against Democrat James Talarico. The state voted for Trump by 13.6 points in 2024, yet it remains one of the races where the outcome could influence the overall chamber control. In Maine, Senator Susan Collins is seeking re-election against Democratic former State Senate President Troy Jackson. The Associated Press indicates that economic strain and tariffs have made the state competitive, with Collins having won the 2024 presidential vote by 6.9 points.
New Hampshire is another open seat race where Democratic Representative Chris Pappas is competing against former Republican Senator John E. Sununu for the seat left by retiring Senator Jeanne Shaheen. The state voted for Kamala Harris by 2.8 points in 2024, making it a key target for Democrats. In Minnesota, Democratic Lieutenant Governor Peggy Flanagan and Republican Michele Tafoya, a former sports broadcaster, are among four candidates vying for the seat vacated by retiring Senator Tina Smith. The Associated Press highlights that this race is part of a broader effort to maintain or shift the balance of power in the Midwest.
Kansas, traditionally a reliable Republican stronghold, has become central to the fight for Senate control. The Associated Press notes that the state voted for Trump by 16.2 points in 2024, but the race is rated as a toss-up to lean Republican. In Alaska, the contest involves a lawsuit filed by the Trump administration related to the certification of the Senate result. The state voted for Trump by 13.1 points, but race ratings describe the contest as a toss-up to lean Democratic, adding uncertainty to the final count.
Financial advantages play a significant role in these campaigns, as the 2026 elections are expected to be the most expensive in history. According to an Associated Press analysis of AdImpact data, Republican committees outraised and outspent their Democratic counterparts, aided by Trump-affiliated groups and Elon Musk. However, at the candidate level, Democrats outraised their opponents. The data shows that 88.1% of Republican general election TV ad spending went to states and districts Trump won in 2024, including more than $850 million in areas where he won by 10 points or more.
Voters are also navigating administrative changes, including a federal judge's order temporarily barring the Trump administration from a plan to prevent noncitizen voting. Critics argue this risks disenfranchising eligible voters, while the administration maintains it is necessary for election integrity. The U.S. Postal Service has added hours and staff to ensure mail ballots are counted on time, a crucial step given the high volume of early voting. Wall Street is also watching these results, as Reuters notes that the outcome could impact investor concerns about AI spending and debt ceiling negotiations.
As polls open, the stakes extend beyond simple party control. If Democrats win even one chamber, investigations and possible impeachment proceedings become likely. House Democratic Leader Hakeem Jeffries has outlined a 100-day agenda focusing on the cost of living and oversight if his party gains the majority. Republican candidates, meanwhile, are bracing for a potential loss in the House while fighting to hold the Senate. The final result will determine who oversees the administration for the next two years and shapes the political landscape for the 2028 presidential cycle.
