Maybe this is naive, but do you not think this election is *already* about Kamala Harris?
I mean, if Biden stays in and wins, he'll be in his mid-80s for his 2nd term. I feel like the 25th amendment almost inevitably comes into play, if we expect Biden to decline further than what we've seen recently.
So anybody voting for Biden now has to ultimately have Harris as a very likely successor, no?
If so, I feel like there's at least an argument to be made for her to take his place now.
