My crazy idea here is maybe the DNC should run candidates people actually like. There's no way in hell if they ran a primary Kamala would have won the nomination given how unpopular she was as VP.
Find me one Kamala voter as excited for her candidacy as the average Trump voter was for him, and I'll find you a dozen who were only supporting her because whe wasn't the other guy. Same story with the Biden campaign in 2020 and Clinton before that.
