The party with which Sanders is affiliated (the Socialists) is called the "Progressive Coalition" party. It solely exists in VT and has several legislators and the Mayorship of the largest city of Burlington. So even in this case, they don't have the cajones to officially call themselves the "Socialist" party.
They're all Marxist commies to the core and there's nothing honest about them in the least. I love the fact that Dean and Leahy slapped Bernie in the face. Implode you leftist scum. There's no place for you in a republic.
Er, in case that wasn't clear, I meant those final comments for Dean, Leahy, Sanders and ilk, not you two.
