I’m not familiar with the WFP.
But my intuition says their goal is to transfer OUR tax dollars to THEIR pockets.
From Wiki: New York's Working Families Party was first organized in 1998 by a coalition of labor unions, ACORN and other community organizations, members of the now-inactive national New Party, and a variety of public interest groups such as Citizen Action of New York.
The WFP claims to be national, but I only see them here in NY, where multiple "parties" can support 1 candidate. They are the "party" of SEIU and the public sector unions mainly. I would imagine also having their own party allows them to spend money with less regulation on their socialist causes also.
