Part of the gender differences in voting you discuss though are influenced by race. Because of higher rates of criminal convictions and apparently disinterest, black and Hispanic males vote at a lower rate than their women. In 2008 the turnout for black women was about 8 points higher than for black men, and turnout for Hispanic women was over 5 points more than for Hispanic men. This sort of disparity existed in 2012 also.
Because of that, minorities make up a larger percentage of the female electorate than they do of male voters. Yes, women as a whole voted for Obama, but white women voted both for McCain and Romney over Obama (and by even larger numbers if you only count married white women). If your wife is white and voted for Obama, then she was the exception, not the rule. You shouldnt try to extrapolate your wifes failings to all women. Women make up a large chunk of Freepers for example and surely you wouldnt claim that Freepers are only guided by emotion.
Thank you for this info. I will look into this.
