The Democratic Party owes nothing to the Clintons. Hillary committed the unpardonable sin of pushing everyone else out of the way only to lose to Donald Trump. They'll never be in a position of power. They have nothing to offer. Plus, Hillary won't shut up! She's still hogging the spotlight. The Dems need new blood. Under the bus they go.
Until the DEMS get enough new blood in the party leadership, they are stuck with the Clinton’s because of the FBI files Hillary had illegally.
