On Jan. 20, Rep. Julia Letlow (R-La.) announced that she will run for the U.S. Senate in Louisiana this year, joining 14 other members of the U.S. House of Representatives who have also announced a 2026 U.S. Senate campaign. 

The fourteen other members are Reps. Harriet Hageman (R-Wyo.), Jasmine Crockett (D-Texas), Seth Moulton (D-Mass.), Wesley Hunt (R-Texas), Ashley Hinson (R-Iowa), Barry Moore (R-Ala.), Mike Collins (R-Ga.), Earl "Buddy" Carter (R-Ga.), Raja Krishnamoorthi (D-Ill.), Robin Kelly (D-Ill.), Angie Craig (D-Minn.), Andy Barr (R-Ky.), Haley Stevens (D-Mich.), and Chris Pappas (D-N.H.).

The 15 U.S. House members retiring to run for the U.S. Senate this year are the most to do so since at least 2012.

So far, two upcoming U.S. Senate primaries have more than one U.S. House member running.

In Illinois, Kelly and Krishnamoorthi are competing in the Democratic primary on March 17. Eight other Democratic candidates — who are not members of the U.S. House — are also running for the seat. Incumbent Sen. Dick Durbin (D) is one of nine incumbent U.S. senators e who are not running for re-election. As of Jan. 27, three independent race forecasters have rated the general election for the seat as a Safe or Solid Democratic.

In Georgia, Carter and Collins are competing in the Republican primary on May 19. Seven other Republican candidates — who are not members of the U.S. House — are also running for the seat. Incumbent Sen. Jon Ossoff (D) is running for re-election. As of Jan. 27, three independent race forecasters have rated the general election for the seat as a Toss-up.

In Texas, two U.S. House members are also running in opposite primaries on March 3 for the U.S. Senate seat. Crockett is running in the Democratic primary, and Hunt is running in the Republican primary. Two other Democratic candidates and seven other Republican candidates are also running for the seat. Incumbent Sen. John Cornyn (R) is running for re-election. As of Jan. 27, three independent race forecasters have rated the general election for the seat as a Likely Republican.

Including special elections, there are 35 U.S. Senate seats — 13 Democratic-held and 22 Republican-held — up for election this year. In the 2024 presidential election, President Donald Trump (R) won 22 of the states holding U.S. Senate elections this year, and Kamala Harris (D) won 11.

Additionally, the two states that use the congressional district method in presidential elections are also holding U.S. Senate elections this year. In Maine, Harris won three electoral votes, and Trump won one. In Nebraska, Trump won four electoral votes, and Harris won one.
