AEI's Karlyn Bowman and Andrew Rugg catch something I haven't seen anywhere else: New Jersey Republican Gov. Chris Christie would be much more popular if it weren’t for a huge gender gap.

Bowman and Rugg highlight the gender breakdown in this week’s Quinnipiac poll. Christie enjoys an overall approval rating of 47 percent, with 46 percent disapproval. Among men, though, Christie's approval number is 56 percent and his disapproval is number 38 percent. Among women the numbers are reversed: 38 percent approval and 53 percent disapproval.

Here’s Bowman and Rugg: “That’s a 33-point gap. Ronald Reagan won with a 17-point gender gap in 1980 and Bob Dole lost with a 17-point gap, so it isn’t always the size of the gap that’s important. But with women a growing part of the electorate, the Christie gap is something to watch.”

I'd also note that the gender gap narrowed in the 2010 national House exit poll, with women actually voting slightly Republican, 49 percent to 48 percent.

What’s behind the Christie divide? Perhaps it’s his take-no-prisoners attitude. Perhaps it’s his war on the teachers unions. Whatever the reason, those numbers do make one wonder how well the Christie brand stand up over time.
