Or, so say my friends and relatives in SC who have been involved in election campaigns for several decades and keep a close watch on what the democrat machine there tells the faithful.
YMMV, etc.
The Establishment is now thinking seriously about supporting Hillary. I'm not joking--remember Mississippi. They'll do anything to avoid an insurgent outsider like Trump or Cruz. An outsider threatens the establishment's existence, but they can do business with Hillary.
There is no real Democrat machine in SC. Harpootlian works hand in glove with the Establishment.
