By winning the battle, they may lose the war. If Republicans do come up with a replacement for Obamacare, it might prove their undoing. A news article says a recent poll suggests only one in four Americans favor one of the proposals for replacement.
That doesn't bode well if the idea is to earn votes in November. The Republicans are in a little bit of a pinch here. The vowed to get rid of Obamacare, but when it came time to do it, they were forced to realize that doing away with some of the things in Obamacare will be unpopular.
An estimate 23 million people's insurance could be impacted. Can the Republicans afford to write off 23 million voters? And, I suppose there are other features in the proposed law that could be unpopular.
The lesson to be learned is that once you give something to the public, it is a hard thing to take it away.
