NC Senate Seat Just Became a Lot More Vulnerable

On Sunday afternoon, Republican Sen. Thom Tillis announced that he would no longer seek reelection to the seat that he has held since 2014. In so doing the Senate seat most vulnerable to flipping to the other side became even hard for Republicans to hold. (The next two seats are Democratic-held Georgia and Republican-held Maine, followed by a rather precipitous drop-off to the next tier of seats.)
