my guess... Liawatha... depending upon how trump does. Bernie was on the right track sort of with the for the common man theme before hellery shot him down.
Re Liawatha...if she ran and lost, a Mooch run would make three women candidates in a row, in a party that is currently at least paying lip service to the notion of bringing white men back into the party. I think Barry’s gang would oppose a Fauxcahontas run for that reason.
The rats are fractured right now, so the infighting could get interesting.
