I do not know a single Republican who ran on the platform of fixing Obamacare. All I heard were a few "Repeal"s and a lot of "Repeal and Replace". Didn't hear any calls for 'Fix Obamacare'.
One might loosely equate "fix" with "repeal and replace."
Trump campaigned that he liked the mandates. No surprise here that you agree with Trump.
And he also campaigned that he didn't like them -- what he said, and to whom, depended on the exigencies of the moment.
What's frustrating is that the ACHA does not do what Republicans have been promising to do for the last seven years. Not even close.
To be fair, as for those alleged promises, I think a lot of voters heard what they wanted to hear, rather than what was actually said.
But as the saying goes, "politics is the art of the possible." The reality was always that they weren't going to do what
some Republicans promised to do, because they were never going to have the super-majority necessary to do it. The Democrat push-back was predictable, as was the disagreement between the FC and the moderates about what was happening.
Particulars aside, something like the AHCA is the most we were ever going to get. Of course, at the moment what we've (still) got is Obamacare.
