WASHINGTON, D.C.  (AP) Former Vice President Joe Biden is running into immediate headwinds from some progressive Democrats from the party’s left wing as he launches his 2020 presidential bid. A group aligned with New York Rep. Alexandria Ocasio-Cortez called Justice Democrats says Biden is a centrist Democrat who could “divide the party” and could squelch progressive enthusiasm for policies like single-payer health care and a Green New Deal. Biden joined the crowded Democratic presidential contest this morning.
