Seems a little sketchy that Pete would drop out right before Super Tuesday after winning two states. I wonder if the DNC is twisting arms to concentrate the "moderate" vote against Sanders.
One source I read called it a strategic withdrawal. As in narrowing the field of moderates so one can can emerge against the unstoppable Bernie.
If you ignore the delegate count so far and look at the votes, the moderates combined have about twice the votes that Warren and Bernie have.
Will it work? No idea. Hope you are stocked up on popcorn for super Tuesday.
