Eh, we need to stop pretending like the only gettable votes are closet Republican racists. There are a lot more Democrats than Republicans, and Trump has turned off even more. Obama won twice and Clinton still beat Trump by millions of votes, and Clinton had a whole host of other issues more relevant than her gender. Non-white and women candidates are viable. Yeah, every vote is valuable, but Biden’s been losing basic Democratic groups that Harris (or really any replacement) can reconnect with and juice turnout.
