How will Democrats fare in the 2014 elections?
Depends on how much Obamacare has hurt the voting population by November.
It shouldn't come as a surprise that more voters support "fixing" something than repealing a law; as any professional wordsmith can tell you, it always sounds more constructive to fix something that's broken. But it doesn't address how voters dissatisfied with the health care law will act when given the choice between a lawmaker who voted for a broken law and a challenger with the freedom to run against it however he sees fit.
We had to pass the law to find what's in it - lots of angry voters.
