Former Secretary of State Hillary Clinton has been accused of just about every dirty political trick in the books throughout her career — and according to outraged supporters of Democratic presidential rival Bernie Sanders, her campaign was back at it again yesterday in Arizona. The Arizona Democratic Party has officially announced that it will be investigating multiple accusations of election fraud across the state’s Democratic primary vote Tuesday, where voters who claimed to have previously registered as Democrats say their party affiliation was unknowingly changed to independent– and therefore, they weren’t allowed to cast ballots in the closed primary.
