Lol, I have heard that people are... ahem.... upset with Mr. Trudeau, to say the least. As for the third party candidates here, it's basically what you said. There is what some would call a concerted effort to keep them out of the debates, and a general bias against them by the media. Typically when a candidate approaches the threshold to be included in the debates, which AFAIK Ron Paul did recently, they instantly revised the rules to keep him out. There's a youtube video you can probably find pretty easily that details a pretty clear media bias against Dr. Paul.
