I agree that women do want to be involved in politics, but I think there are still some systemic barriers to becoming candidates that need to be considered. I agree that it's not that the public doesn't want to elect women; we don't find any evidence of that.
However, there are things to be thinking about. A simple one to think about is child care. The difference is in provisions of making sure that all candidates would have access versus not. There are also personal costs, obviously, to being involved in politics, and the extent to which those are unfairly or unequally distributed on men and women needs to be considered.
There are some general policies that could be put in place that might encourage more women to get involved.
