There are only 76 women in the House out of 435 —- 17%. 59 of them are Democrats and 17 are Republicans. Three of the Democrats are non-voting members (DC, Virgin Islands and Guam.)
Out of the 56 women in the Democratic caucus, only two voted for Stupak. All 17 Republican women voted for it.
What this adds up to is that 97% of the Democrats who voted for the Stupak amendment were male. 90% of the Republicans were male.
I would have to guess that if more than 17% of the congress were women, there would be a little bit less likelihood that women’s rights would be so often used as a handy tool to placate neanderthals. That’s just a guess. Habits are hard to break.
