Half empty? Try 3/4 empty! What did she have to do to bus in the few people stupid enough to show up?
I think the truth is that her whole base has always been the illusion many people suspected and it is ALL astroturf.
I mean look at DU. When slick over there posted his little picture backing hillary, he had a damn near mutiny. I think the arena was that empty because she does not have enough cash even with the clinton foundation, to fill them all and she cannot go from full to empty to full to empty without being obvious even to her droids that it’s all a lie.
So she will play until she is paid to go away.
