Bush's favorability was 50/28% in their October 2014 poll, and now it's 43/45%. Pretty remarkable collapse, given how the campaign is still in the early stages.
Yeah, I'm curious what's driven it. Bad press for his fumbled Iraq answer? Maybe his immigration views becoming better known?
It's definitely a puzzling question. I don't think the latter is enough to change voter's minds nor do I think that has happened. It could be a good bit of the first though. Even if they support Iraq as much as people say they do, they may not see this as a winning strategy. Beating Clinton after 8 years of Obama seems to be pretty important. Moderates that can't win are useless if a more conservative candidate stands a better chance.
It may just be horrible press in general. Plus he's considering skipping Iowa. They can't take too kindly to that. Gotta make nice with those voters. (Though they are falling everywhere so more of the horrible press in general)
