Liberty Union Progressives evolved from the group Buffalo for Bernie.
It is run by Charles Hess, Sara Palmer, and Matt Dearing.NYPAN, the New York Progressive Action Network, was founded in December of 2016, following the 2016 elections. The founding chapters were all grassroots organizations that had formed during the Bernie Sanders campaign in New York. Volunteers in these organizations, many of them entirely new to politics, became heavily involved in their communities, built networks and made lasting friendships. At the Democratic Convention in Philadelphia, representatives from these grassroots organizations met up and decided that, even though the primary was over, the movement was too important to abandon. They chose a time and location to meet again, back in New York, where they voted to incorporate and set up a 501(c)4 organization.
