Women are far more likely to be partisans than men. This surprises me, and I can't come up with a good, theoretically sound reason for it. It is well established that women lean disproportionally towards the Democratic Party and men towards the Republican Party, but it also seems as if women lean towards partisanship in general, at least when compared to men. Think of it this way - women are just as likely to be Republicans as men are, but they are far more likely to be Democrats than men. And this pattern is consistent regardless of age or income.
