(Politifact) Joe Biden is pushing back against the perception that hes not progressive enough for todays Democratic Party. Long seen as his Achilles heel in this Democratic primary Bidens 35-year Senate voting record reveals a history of breaking with liberal orthodoxy on a variety of issues from his vote to authorize the Iraq War to his backing of measures that led to mass incarceration. Biden in a recent interview sought to turn the narrative on its head by claiming progressive credentials. I was always labeled as one of the most liberal members of the United States Congress the former Delaware senator told ABC News in an interview that aired May 1. After a review of sources that grade lawmakers based on ideology we found Bidens claim to be inaccurate. By a variety of measures Bidens record has been that of a moderate Democrat.
