I'm not trying to absolve anyone, but Paul Ryan bears the primary blame, and there's no doubt about that.
However, it can't be reasonably argued that President Trump is trying to sabotage Paul Ryan, but the converse is eminently possible, if not highly probable.
The tax cut issue should be an easy win, absent GOPe sabotage. So Congress needs to get its ass in gear and deliver. They're the governing majority now, and acting like an opposition party is not a legitimate role for them any longer...
RIght—Ryan is not Trump’s friend.
But the buck stops with Trump and he is the one who was elected nationally, and the larger blame IMO rests with him.
He chose, and he chose poorly, and now he is compounding it by using it as an excuse to ally with the Democrats, rather than the conservatives, in Congress.
