I want Tester and McCaskill and Bill Nelson and Sherrod Brown to win. They're arent freshman senators like Heitkamp, Donnelly and Carte Goodman, will be. They've been through this before. I am not completely sold on Dean Heller winning easily over a Dina Titus, either. But, Emily Cain will pick up the King seat, since he will be the first retirement other than Hatch.
Even if he does - nobody can guarantee her win. Both LePage and Poliquin are quite able to beat her, especialy in midterm year. In fact - Poliquin already beat her in 2014. Of course, Maine as a state is more liberal then ME-02, but there are no guaranties of Democratic win there in 2018
