A general in war, and, this is a quiet revolution, does not always get to pick the time and place of a battle. The case came up now and Trump’s generals had no choice but to respond to it now. To take the opposite tact, supporting Obamacare in any form, would have demoralized his own forces and caused more damage than sticking with the strength of his polices and convictions. Sometimes you have to trust the voters to see past the one or two things they like to view the larger picture.
Now would be the time for Trump’s generals, whoever leads various efforts, to stress what he plans to replace Obamacare with. He needs to go on the offensive. “Tweets away!!!”
While it is an issue,it is not presently an issue that overshadows all the other more stridently visible stuff.
In short, old news
