I'm still waiting to see what happens in 2018, but the election in Alabama doesn't worry me too much. The numbers still do not favor the regressives, so I'm pretty sure democrooks lose seats. For that matter if Jones wants to get re-elected in Alabama he might want to get on board with the GOP and be the one "maverick" that will of course not be exalted like McLame.
The numbers overwhelmingly favor Republicans. They only have to defend nine seats and most are in Red States
They will have to screw up very, very badly to lose the Senate
That is where Trump and Bannon come in.....
If Trump enters 2018 with a 30% approval and the election becomes a referendum on Trump....Republicans can lose badly
If Bannon primaries sitting Republican Senators and replaces them with batshit crazy idealists...Republicans will lose
