Hard to say. We haven't seen women's issues be a dominant factor in a presidential election since when? I do think that is very motivating for a substantial swath of the electorate, but the economy and immigration seem to rank higher. Of course if Harris can just hold her own on the economy/immigration and not get obliterated on those issues, then it would help her chances. The exit polls will be interesting.
I remain confident that women's rights will be the deciding factor in this election. Women are upset and motivated (as they should be) and they have far more at stake this election than men. I think turnout will overwhelming reflect that. I suspect Trump's closing arguments these last few weeks have not been helpful towards persuading women voters.
In hindsight it will seem obvious. Kamala is dominating in fundraising, get-out-the-vote efforts, enthusiasm, and rally sizes. Trump is pursuing low-motivation young males, dressing up for Halloween, and campaigning in New Mexico and Virginia.
When Georgia and the Blue Wall go to Kamala, it will be specifically attributable to motivated women.
