All early voters count as one vote each—the demographic analysis is irrelevant imho.
That is busy work for “experts” who try to baffle us with bull-hockey.
No you can do simple math on it. If you believe Kamala is getting 56% of women’s vote and 57% of male vote you can apply statistics on those numbers and see who is “winning”.
But yes we don’t know if Kamala women or Trump women are more motivated to go vote...same with men. But one can apply common sense and women who love abortion will turn out for Kamala.
