The gap reappeared in force in 1996, when Clinton won women by 16 points and lost men by one point, for a 17-point gap. In 2000, the gender differential expanded: Republican George W. Bush lost women by 11 points and won men by 11 points, for a 22-point gap, the widest in modern times. Winning re-election in 2004, Bush improved his standing among females, losing women by only 3 points and winning men by the same 11 points, narrowing the gender gap to 14 points.

This year in Ohio, Obama beat Mitt Romney by 11 points among women and lost men by 7 points among men, producing the same 18-point gender gap in this critical swing state as in the nation as a whole. In both Virginia and Florida, the gap was 13 points. In Iowa, it was 19 points and in New Hampshire it hit 20 points.
Obama won women and lost men in every swing state except Colorado. In Colorado this year, Obama actually did better among men, winning them by 5 points, than women, winning them by 2 points, a narrow 2-point gender gap. Four years before, Colorado had a 16-point gender gap, with Obama winning women by 15 points and losing men by one point.
In the one swing state that Obama lost -- North Carolina--the gender gap was 11 points, with Romney making up for his narrow 2-point deficit among women with a 9-point lead among men.
