I would have to say of the small groups out there only the American party of labor has any real chance of becoming a vanguard party in the United States. With that said I don't think they will be increasing in size anytime soon, unless they are able to actually come up with radical new ideas that have not been tried before. They at least they'll have a party platform which is much more than what I've seen from the largest so-called communist group, the Communist party of the United States.
Sample of the American party of labor' platfrom
Workers
1. We demand that all means of production be in the hands of the working class through the socialist state, represented through worker councils or elected managers with production estimates provided by the state.
