23 of the 52 Republicans who voted to acquit Trump in his impeachment trial are in seats up for election this fall. Many of them are in deep red states, but some are highly vulnerable. There are 7 races across 6 states that will make or break the Senate majority. Each of these states leans red, except maybe Maine.

There are nominee funds in each of these battleground states.

Democrats are starting to pull ahead in some key races where Republican incumbents are on the ballot, so pay attention to these seven races:

Susan Collins in Maine (she’s been there 24 years)

John Cornyn in Texas

Steve Daines in Montana

Joni Ernst in Iowa

Kelly Loeffler in Georgia (special election)

David Perdue in Georgia

Thom Tillis in North Carolina
