x. the established DNC types like their jobs. it's really that simple i think.

someone like bernie who potentially could've gotten in there to fire consultants, staffers, etc. and hire people that actually give a fuck is a threat.

as far as winning/losing elections, they prefer to win. without a doubt. more campaign/party donations from pacs and corporations, more lobbyist bribes. but everything always goes back to x. above.
