Comment: Life is politics.  Sometimes aberrations rise to the top in the political realities we exit within.  There have been many, and Trump may be or become the most aberrant.  
But, life is still politics.  This healthcare thing is a powerful lesson in that.  
Trump took a political "certainty" (repeal of Obamacare by a GOP that controlled both houses of Congress and the WH) and politically undermined it.  
It started back in 2016, when he turned repeal into an unthinking imperative.  That was a mistake born of ignorance.  He did not understand healthcare complexities.  He (and the GOP) should have heralded a more deliberate approach instead of an "immediate" "first act on first day of my Presidency" approach.
Along the way, he cemented the failure.  He attacked so many, it is surprising 49 GOP Senators actually voted "Yes" last night.  Ultimately, his misogyny and politics of personal insult lost him Collins, Murkowski and finally McCain.
It will get worse
We shouldn't elect aberrations.
