I imagine Obama’s folks and Soros’ folks TOLD Biden to pick Harris, or else. The elite apparatchiks of the Dim party - in charge from no matter where is their known party or other public or private position - tell the Dim’s who to pick. If they don’t listen they will unmask them with all the dirt they have on them. Political blackmail within the “party”. Steyer is one of those “in charge” people in California and he more or less signaled to the party it was time to unleash all the dirt the party already knew about Swalwell.
Obama was every bit the puppet that Biden was. Guy hasn’t had an original thought in his life.
So THAT is what happened with Swalwell. I was wondering why the knives were out for him all of a sudden. Normally the dims go all out to protect one of theirs. He must have really pissed someone off.
