There is strong evidence to support the accusations that former DNC chairwoman Debbie Wasserman Schultz helped rig the Democratic primary. Debbie Wasserman Schultz is very close to Hillary Clinton; leading many to suspect that she would help Clinton's presidential campaign. Hacked DNC emails now reveal that many party leaders were in fact trying to undermine Bernie Sanders' presidential campaign in order to help Clinton.
I'm sure the Dems thought Bernie had no shot in hell. They probably did plan to ensure he didn't win the nomination. Assuming Debbie Wasserman Schultz actually did try to rig the election, given what's happening now, she might have just given Drump the presidency. The Bernie people are out of control and are not voting for Hillary, so we're all screwed.
The DNC, under Debbie Wasserman Schultz's leadership, set out to influence the public discourse surrounding the primary challenger to Hillary Clinton, Bernie Sanders. However, to call this "rigging the election" is an overstatement; most likely, her efforts had a negligible impact on the votes of Democrats across the country. Nevertheless, her misconduct appropriately resulted in her resignation; this is deplorable and yet another example of the embarrassing state of American politics, adding to the woeful reality that we must choose between a liar and a buffoon.
Resigning Democratic National Committee chairwoman Debbie Wasserman Schultz is accused of rigging the election. I very much doubt that she did, as she is only one woman, and I imagine that it would take a lot more people to rig an entire election, but at the same time politicians are not to be trusted.
