Fox News Undercard Republican Debate: Live Coverage

Carly Fiorina just went after Hillary Clinton and Barack Obama on the importance of climate change. That’s not really much of a surprise. Just 20 percent of Republicans think global climate change is a very serious problem, according to a 2015 Pew Research Center survey. That contrasts with the 68 percent of Democrats who think it is a very serious problem.

Q:Historically speaking, what’s the lowest any candidate has been polling nationally at this point before coming back to win the nomination? — commenter Peter Nygaard A:Peter, looking it up, I believe the answer is George McGovern in 1972. He scored just 3 percent in a Gallup national primary poll a few weeks before the Iowa caucuses. Jimmy Carter was only at 4 percent at this point in the 1976 campaign.
