Too bad. It’s none of his business (constitutionally) and he needs to get over it and go to full repeal before it destroys the rest of his agenda.
By the way, I meant too bad for Trump not too bad the elderly people and others you referred to in your post.
Trump the president is a different entity from Trump the candidate. The president is required to faithfully execute the office of the president to the best of his ability and to preserve, protect and defend the constitution.
I just saw a poll that only 7% of Americans think repealing Obamacare is the top issue (5th place). The top concerns are jobs and tax reform. Trump is right to leave it for now and concentrate on the rest of his agenda. IMHO getting stuck on healthcare will sink the rest of his agenda, and make him a one termer. Time to move on and come back to it later.
