I know people in this party and right now it's very hard to even get them to ADMIT that Biden was losing this election long before he went on TV and started talking like the worst mumble rapper in history.
The numbers don't seem to phase them.
2020 was a winning campaign, and it would win again if you had a credible person promising those same things - but to be CREDIBLE, Harris (and it will be Harris) has to admit Biden didn't do it and say "but I'm not him."
That's not how Dems roll.
