For some, I think, it is all about identity.
If the bill is Trump’s, Trumpcare, it is brilliant and we must get behind it, unless we are traitors to the nation. If the bill is Ryan’s, Ryancare, it is bad and proves once again that the GOPe are just a bunch of socialists like the Democrats.
It’s easier if you define the two sides in play as “Trump” and “UniParty”. The UniParty includes Democrats and GOPe. Trump is most of America.
