The entire election boils down to a few key swing states. Biden was well down in most of those.
When someone is down by percentages that are outside the margin of error, and there were multiple states like that, even the potential for the holes in the Swiss cheese to line up exactly right gets narrower and narrower.
I think it’s safe to say that the race has gone from slim chance before the debate to no chance after the debate to no fucking chance in Hell after the assassination attempt & RNC to Trump is running scared after Biden dropped out and Harris has emerged as the front runner!
I was a big supporter of hers before the Dem debates 4 yrs ago. I changed my tune when I saw and heard the rest of the field, because I thought others were stronger and better prepared for the role. Today, though, with 4 yrs of VP under her belt, I think she ticks all, or most of, the boxes needed to bury Trump IF she can pick a VP nominee who helps win her key swing states. Kelly of AZ looks like the one to me.
