I think you overestimate how many women will simply prefer a woman leader by default. Several countries have had women as their PMs/leaders before and they don’t automatically win every woman’s vote each election cycle.
What’s going on here in the US is just pretty cut and dry: If you value women having bodily autonomy and equal rights, then the choice is pretty damn clear on who you should vote for. Unfortunately, it feels like so much attention is on the presidency, this obvious connection isn’t being evenly applied to other political offices as well (i.e. last I’d read, all projections have the GOP winning the Senate).
They like it because they either work for it or hope to work for it and be in a position of power.
