Bernie Sanders, a self-avowed socialist, praised policies once deemed too radical that are now mainstream in the dem party. Socialism never works out in the long haul, just look at Venezuela! With so many still supporting Sanders and now policies he pushed being supported by the party, it's safe to say the dem party is a socialist party.
With so many still supporting him and these policies now part of the party, how did he lose the 2016 primaries?? Oh wait he didn't, Hillary stole the primary from him with her "super delegates".
