Ten Senate Races Will Decide Control of Congress in 2026 Midterms

Voters across the nation are heading to the polls on Tuesday, November 3, 2026, to decide the control of Congress halfway through President Donald Trump's second term. The Associated Press notes that this midterm election is being viewed as a referendum on the administration, with many citizens citing high prices and an unpopular war with Iran as primary concerns. More than 57 million people had already cast their ballots as of Monday, surpassing early voting totals from four years ago in many closely watched states. The outcome of these elections will determine which party holds the majority in the Senate and the House of Representatives for the president's final two years in office.

According to Ballotpedia, 35 of the 100 U.S. Senate seats are up for election. Republicans currently hold 53 seats, while Democrats hold 45, plus two independents who caucus with the Democrats. For Democrats to gain a majority, they need a net gain of four seats, meaning Republicans can afford to lose only two. In the U.S. House, all 435 seats are contested, with Democrats needing a net gain of three districts to secure a majority. The Associated Press reports that the race is tight, with one or two seats potentially tipping either chamber.

Ten specific Senate matchups have been identified as critical battlegrounds by the Associated Press and PBS NewsHour. In North Carolina, former Governor Roy Cooper faces former Republican National Committee chair Michael Whatley following the retirement of Senator Thom Tillis. In Georgia, Senator Jon Ossoff is running against Representative Mike Collins. In Ohio, former Senator Sherrod Brown is challenging Senator Jon Husted in a special election. In Michigan, former Representative Mike Rogers is competing against Abdul El-Sayed for the seat vacated by retiring Senator Gary Peters.

The race in Texas features Attorney General Ken Paxton, whom President Trump backed in the primary over Senator John Cornyn, against Democrat James Talarico. In Maine, Senator Susan Collins is facing former state Senate President Troy Jackson, with the Associated Press noting that economic strain and tariffs have made the state competitive. New Hampshire voters are choosing between Representative Chris Pappas and former Senator John E. Sununu for the seat left by retiring Senator Jeanne Shaheen. Minnesota is holding a four-way race for the seat of retiring Senator Tina Smith, featuring Lieutenant Governor Peggy Flanagan and former sports broadcaster Michele Tafoya.

Kansas, a traditionally Republican state, has become central to the fight for Senate control, with Roger Marshall running for re-election. In Alaska, Senator Dan Sullivan is seeking another term amidst a lawsuit filed by the Trump administration regarding the certification of the Senate result. The Associated Press highlights that these races are influenced by the new congressional maps adopted in six states following mid-decade redistricting, including North Carolina and Texas. Ohio is also using a new map, which may affect how districts vote compared to historical trends.

The financial landscape of the 2026 elections is described by the Associated Press as likely the most expensive in history. Republican committees have outraised and outspent Democratic committees, aided by Trump-affiliated groups and Elon Musk. However, at the candidate level, Democrats have outraised their opponents. An analysis by the Associated Press of AdImpact data shows that 88.1% of Republican general election TV ad spending went to states and districts Trump won in 2024. This spending strategy reflects the Republican focus on defending their base while attempting to beat the historical pattern of a president's party losing seats in midterm elections.

Voter sentiment is shaped by economic pressures and oversight of the administration. AP-NORC polling indicates that 35% of U.S. adults approve of Trump's job performance, while about seven in ten say the country is heading in the wrong direction. Most voters blame the president for high prices. James Moore, a librarian in Raleigh, North Carolina, told the Associated Press that he is paying more for taxes, healthcare, and everything else. Conversely, Mark Barker of Palm Beach Gardens, Florida, said he has been following Trump and believes he is doing an awesome job. These differing perspectives are driving turnout in key states like North Carolina and Florida.

The administration has faced challenges in election administration, with a federal judge temporarily barring a plan to prevent noncitizen voting on Monday. Critics argue this risks disenfranchising eligible voters, while the Justice Department has threatened to prosecute local election officials. The U.S. Postal Service has added staff and hours to ensure mail ballots are counted on time. In New Hampshire, poll hours vary by town, opening by 11 a.m. and closing no earlier than 7 p.m. In North Carolina, polls are open from 6:30 a.m. to 7:30 p.m., while in Georgia, they are open from 7 a.m. to 7 p.m.

If Democrats win even one chamber, investigations and possible impeachment proceedings are likely to begin. House Democratic Leader Hakeem Jeffries has outlined a 100-day agenda focused on the cost of living and oversight, and would be the first Black speaker if his party gains the House. A strong Democratic night would also boost potential 2028 candidates such as Gavin Newsom, JB Pritzker, and Pete Buttigieg. Republicans are bracing to lose the House while fighting to hold the Senate, with Chairman Joe Gruters stating that everything depends on turnout. The results will also influence Wall Street, as investors watch for signals on debt ceiling negotiations and AI spending.
