If Trump wins, Ryan will step down as speaker. It would mean an adversarial relationship from day 1 which doesn’t help the country.
So, the question is, who should be speaker if Trump wins?
And, who should be the speaker if Clinton wins?
Ryan has just thrown his support behind her. If she wins, Ryan is part of the reason.
There's no way he can remain in a leadership position after doing that.
Hard to imagine the GOP going beyond current leadership:
Kevin McCarthy, Steve Scalise, Cathy McMorris Rodgers, Luke Messer.
Jim Robinson
