It's no secret that some supporters of Sen. Bernie Sanders (I-Vt.) are deeply convinced the Democratic Party's presidential nomination process is rigged, unethical and inherently corrupt.
They've protested front-runner Hillary Clinton's wins in a number of states under the guise that the rules are too restrictive and the party too partial for the results to be valid. Some have legitimate grievances about the primary process, while others are just tapping into conspiracy theories. The end result is the same: increasingly nasty attacks on officials in the Democratic Party.
