It'll be interesting to see what Arkansas does here - I think Democrats still have a small amount of hope here, but Obama winning reelection really did them in. Not sure if they can afford another bad midterm, which is what we'll likely see.
No two term President in over a hundred years has had two bad midterms in a row.
Not really - 1982 he lost seats in the house but not the Senate, 1986 was the opposite.
But if I could, yeah. The only one that would make me consider not voting/voting third party is Cuomo, and that's more down due to the fact that he would cause a lot of harm to the party rather than what he's done.
