What have male candidates done since 2000 in many of these states..absolutely nothing.
Well some, like Walt Minnick, have occasionally won. Maybe Minnick wouldn't have won if he was a woman.
Also, you could apply the same logic to "white candidates", "heterosexual candidates" "college-educated candidates", etc. Democrats keep losing with candidates who live in dwellings? Why don't they run homeless candidates!?!
No, it's a way to posture that you're in favour of gender equality while in fact organising it such that it will do as little as possible towards increasing gender equality in Congress. Doing it in winnable districts is far better, if that's your aim.
Wishful thinking. It's a lot more likely that candidates who gain attention because of their relative novelty (and I don't think being a woman is sufficient to gain much attention) would find that the media focus is almost solely on the personal characteristics of the novel candidate and not the isues. Did Sarah Palin's VP candidacy substantially raise awareness of the issues she stood for? Has any other female candidate?
