In every presidential election since exit polling began over forty years ago, Democrats have performed stronger among women than men, while Republicans performed stronger among men than women. Of the eleven elections since 1972, Democrats have lost the female vote in four (1972, 1980, 1984, & 1988), all of which resulted in electoral landslide defeats for their party. The same is true for the three of eleven elections (1976, 1992, and 2008) where Republicans lost the male vote.
The largest gender gap recorded by exit polling came in the 2000 election, where Gore carried women by ten points, while Bush carried men by eleven.
Yet in an election year where the most likely Republican nominee happens to have a knack for disparaging women, and where the probable Democratic nominee elicits an almost instinctual disdain from her male detractors, you have the recipe for a gender-gap explosion that could make the 2012 election, or even the 2000 contest, seem tame.
In fact, if current polling is any indication, that's exactly where we are headed.
Using national general election surveys released this year and compiled by Real Clear Politics, the average gender-gap across eight surveys is twenty-seven points. That's nearly ten points higher than the gender-gap seen in 2012, five points higher than the largest gender-gap ever recorded in a presidential election, and fourteen points higher than the average gender-gap in presidential elections since 1972.
