I was a Bernie Sanders supporter and am disgusted by the clearly unfair treatment he received from the DNC.  I'm presuming that treatment will lead to a major "revisiting" of the nominating process in the Democratic Party.  It "sure as hell" should.

That said, a Presidential Election is an entirely different process.  It is so decentralized and there are so many systems of accountability with bi-partisan involvement that "voter fraud" at the polls or in the tabulation of votes is virtually non-existant.  I would posit that voter suppression is a far, far more serious issue.  However, this campaign has been so "wacko" that the issue of voter suppression hasn't really be addressed.

The exception, of course, is Trump's call for "poll watchers" to flood the polling places to prevent "massive voter fraud."  This is an invitation to voter intimidation at polling places across the country.  Hopefully those polls will be well staffed and policed to thwart such efforts.
