there is not a better time than know to take Ryan out and replace him than now. Hes wounded, perhaps mortally, in his current position
Sorry, we’re not going to get anybody substantially better than Ryan in that position. Anyway, it’s not going to happen and would be suicide for the mid terms.
If we are worried about mid-terms this early in the game, then we have the same problem just after them going into 2020. Which means it's suicide no matter when it's done.
Ryan is a threat to the mid-terms. The way he’s going, we could see a third party bid.
