First, I might not always teach this in statistics. When you're concentrating on gaps between women and men, the difference between the two of them, we often say that women are less interested in politics than men are, therefore they didn't run. That's true, but that doesn't mean that there aren't a whole heck of a lot of women who are interested in politics and who would be willing to run—and I think that's an important point to make. Focusing on the gap is problematic, as far as I'm concerned.
There are a whole host of reasons why you could say women are less interested in politics, but I think one of them is just this perpetuation of the notion that politics is difficult, it's a war, it's combative—all those sorts of stereotypes. The way it's portrayed in the media, I think, reproduces this notion that this is where men should be and women should be doing other kinds of things. We still have this kind of public-private divide.
