Republicans in the Senate are losing yet another key incumbent for the 2022 election cycle.

Sen. Roy Blunt (R-MO) announced on Monday that he will not seek re-election next year, following fellow Sens. Pat Toomey (R-PA) and Rob Portman (R-OH) out the door.

Former Sen. David Perdue (R-GA) had considered running in Georgia in 2022, but recently decided against it.
