Huge grassroots movements, made up of millions and millions of people, are fueling the fight for a $15 minimum wage, fighting back against fossil fuels and the Dakota Access Pipeline, fighting to end fracking, fighting to remove lobbyist money from politics, fighting to end senseless wars and international violence, fighting for universal healthcare, fighting for the legalization of marijuana, fighting for free college tuition, fighting against systems of mass incarceration, and so much more. But mainstream Democrats arent really a central part of any of those battles, and, to be clear, each of those issues have deep networks, energized volunteers, and serious donors, but corporate Democrats virtually ignore them.
