By the numbers: Senate seats to watch in 2022

While Republicans are giddy about their chances for regaining the House next year, GOP prospects for taking the Senate remain more uncertain, data reviewed by Axios suggests.

By the numbers: At least five Republican senators are retiring after the midterms, and four of their seats are in battleground states. That makes a simple Republican-for-Republican election exchange all the more difficult.

• All told, 20 Republican seats are among the one-third of the Senate up for reelection.
• Meanwhile, none of the 14 Democratic senators up for reelection has announced retirement plans.
• Four of their seats — in Georgia, New Hampshire, Arizona and Nevada — are being targeted by the GOP.

How it works: Axios has used a headshot to chart every candidate whose state was decided in the 2020 presidential election by 15 points or less.
