"If there was any doubt left, MoveOn's endorsement of Joe Biden confirms his sprint leftward in an attempt to appease the radical extremists in his party. The left-wing activists who endorsed socialist Bernie Sanders in 2016 have officially taken the wheel of Biden's campaign. In their endorsement, MoveOn praised Biden for running on the 'most progressive platform' ever, which includes tax increases, the job-killing regulations of the Green New Deal, free healthcare for illegal aliens, liberal judges, and abortion-on-demand. It's no wonder he can't unify Democrats behind his candidacy. Over and over again Biden has proven that he is too weak to stand up to fanatic leftists who are now calling the shots and will expect him to continue to fall in line."
