Disliked Biden, hate Kamala. Voted for them. Kamala and anyone else, nope.
They need someone hopey and feely like a 2008 Obama. If they don't find that, the Dems are toast. And I can't think of any mainstream politician that could get that reaction apart from maybe AOC. But that would get just as many MAGAs on the other side out to vote and they'd still lose.
You need empowering Democrat that is neutral to the MTG loving republicans.
Maybe Newsom? But if I had to bet it will be Kamala and another woman or minority to get the double whammy and they'll surely lose.
