I agree with EG, it annoys me a lot to see people saying: "Johnson is doomed", "Kirk is doomed", "Heitkamp is doomed",...
Okay, present a way that Johnson is doing totally fine and is popular, and will win re election in 2016 regardless of a Feingold run. Entertain me.
Well, before this scandal, there was no obvious Democratic replacement for Feingold, Johnson's approval ratings were fine, and he was able to self-finance. After the scandal, who knows, but prior to this Johnson was definitely favored to be reelected.
