The number of senators not running for re-election in 2024 is tied with the number who had announced they would not run at this point in the 2022 cycle, and higher than the numbers for 2020 and 2018. On the House side, the number of members not running is lower than the number at this point in the 2022 cycle, but higher than 2020 and 2018.
In total, 16 members of Congress—five senators and 11 representatives—have announced they will not seek re-election in 2024. The members of Congress not running for re-election include 12 Democrats—four in the Senate and eight in the House—as well as four Republicans—one senator and three House members.
Five senators had also announced they would not seek re-election at this point in the 2022 election cycle. Four had announced at this point in the 2020 cycle, and none had announced at this point in the 2018 cycle.
