You really are not a Democrat and you don't understand the downside of Socialism (and it's huge).
That you ask why Dem staffers would quit before they aligned themselves with the Socialists informs me that you have a lot of learning to do. I've given you researched facts, antidotes and provided you with resources in the past and backed them up with facts and quotes. Apparently you are happily, blissfully ignorant and like it that way. Good luck with that.
