What underhanded bullshit? No elections were rigged. A few very bad ideas were suggested and then shot down because they were very bad ideas. It's clear that the party had a preference and it's also clear that it played fair anyway. The "media manipulation" stuff has been misread. If you don't think people and organizations don't push back when they think they've been treatedly unfairly by the media, you haven't worked in the media. They're always going to complain and try to get their side of it out there.
Also, if these leaked emails come from Pooty Poot, how do we know they haven't removed information that would cast the events in a better light? They could have selectively edited them to present the picture they wanted. They almost certainly did.
