As usual, the Trumpbots absolve Trump from all fault (which is itself ironic after the Madrassa Messiah years), but they are imo partially correct in that Trump's EOs are aimed at congress.
A president typically has a duty to set a legislative agenda with parameters of what legislation should accomplish, and there cannot be any factual dispute he failed to do that. Ryan cobbled together a bill that cut Medicaid funding enough to get the Freedom Caucus, and Trump praised the bil until it got to the Senate where it became a "mean" bill. And ultimately the Turtle couldn't get 50 gop votes because the senators simply didn't trust the House on Medicaid and weren't inclined to take whatever came out of a conference.
But Trump's failure doesn't absolve Mitch and Ryan. I'm honestly surprised they gave Trump as much deference as they did; they pretty much treated him like a "real" president, even though they had to know doesn't have any conservative ideology for them to find common ground. And, he tasked them with an impossibility - congress cannot totally rewrite healthcare policy in one day ... or six months. McCain is right. Congress was created to follow a process to achieve legislation, and that process was totally ignored especially in the Senate

I thought Mitch would march his merry was as majority leader to enact a republican agenda without allowing Trump to have much of a role in legislating, and just present him with bills to sign.
And in the end, the 30-35% of Trumpbots will continue to absolve the Orange Orb of incompetence and probably election crimes.
