John McCain runs on hate, you can't read much about him before coming to the simple conclusion. Bottom line, it's miraculous he has not publicly exploded of late. With almost a full month to go until the election and his campaign doing a credible imitation of the stock market, however, there's still hope. Brave New Films, the folks who brought you the acclaimed documentary "Walmart: The High Cost of Low Price," has assembled some people willing to go on the record about witnessing his rage episodes. They're worse than suspected. In the video, a credible witness claims he back-handed a female POW-MIA advocate named Jeanette Jenkins so hard she spun around and hit the wall. They show a copy of her subsequent complaint to the Senate Ethics Committee.
