In general, I believe a two woman ticket would get fewer votes than a woman/man ticket, which would get fewer votes than any male-led ticket. The misogyny effect is strong. But it really depends a lot on the specific people.
Considering Hillary won the popular vote, I think most people don’t consider gender very important. Or at least the people who do consider gender very important are voting Republican anyway.
Could? Possibly, sure.
Would? Why should any ticket guarantee a win based solely on arbitrary characteristics of the candidates? Nothing about being a woman, a man, trans, cis, gay, straight, bi, ace, black, white, Latino, Asian, biracial, triracial, short, tall, hirsute, bald, balding, skinny, jacked, overweight, or any other randomly chosen descriptor should be a factor in electability. The fact that it’s even in question is a strong indictment of how we view politics in a broad sense.
Gender is not a relevant consideration for the Democratic Party.
Imagine genuinely thinking this.
Which women? What are their voting records? What experience do they have? Can they work with the other party if they need to? Are they respected by foreign leaders?
If it’s this election, are we sure putting them on the ticket will survive certain legal challenges?
Too many questions without enough answers.
Generally speaking though, no, I don’t think it would happen. I would totally support it, but I think there are too many misogynists out there. On the other hand, I never thought there would be a Black president either.
