I think, going along with what you said, that it was aimed at the dems gathered for their dinner.
I'm guessing there is a power struggle for leadership and it's coming from Harris and Warren.
Guessing, too, some experienced dems balked and the dinner was arranged to get them in line.
Voter fraud message was aimed at releasing the Jones/AL story. Jones is a accident waiting to happen and it's looking like having him seated was a good chess move.
Experienced dems told Harris/Warren to fuck off. Will have to see the 81-18 break down to see who the 18 were. I'm thinking 18 is Harris group.
