Kamala Harris was the favorite to replace Biden by a fucking light year. She was poised to immediately take over his entire campaign apparatus and his money, which no other candidate could do. Pundits all around were speculating she’d get the nomination, and were widely reporting that Democratic politicians they spoke to also believed that. The only question was whether Biden would endorse her immediately or withhold an endorsement, and he chose to endorse her immediately. I just don’t buy anything of what you’re saying here.
