I've been wondering how McConnell and the other Republican heavyweights feel every time Trump tweets (or re-tweets) some truly foul thing(s) like the above. Surely, any decent human being's reaction has got to be "oh, for chrissake! This is the President???!!?!?!?" And for those Republicans to realize that this guy is also the head of their party, the guy who represents them- that must, on some level, make them wonder just what the **** it is they're doing when they keep propping him up. Is it really too late for them to just cut their losses, admit out loud what a lot of them have to be thinking to themselves ("what a moron!"), and hope for a better figure-head the next time around? Surely just about any other Republican can get their policies passed, if the policies are that good? Or do they just shrug and say "well, it was a winning strategy before, so what the hell..."?
Well, those are mostly rhetorical questions, I guess, especially the last- they don't care about policy, they care about politics, and winning isn't everything, it's the only thing that counts in that.
