Former Secretary of State Hillary Clinton accused Sen. Bernie Sanders and his support network of being responsible for disunity within the Democratic Party. In a Friday podcast, Clinton called the behavior of Sanders supporters "distressing," assigning blame to them for the outcome of the 2016 election. . . . Clinton additionally categorized the first-in-the-nation caucuses in Iowa, where some polls show Sanders in the lead ahead of Monday's event, as being "undemocratic." She criticized how the caucuses limit voting to one evening, claiming it prevents Iowans with night shifts from voting.
