There's such an aggressively apolitical movement in the US that anything that smells of being political - even the term "political" is so ridiculous, when you think about it. The worst part of governing, the political side, is the grossest part, so that's what they call it. So anything that reeks of that immediately gets tuned out by 70 percent of the population.
I think American culture had just become so disengaged from the process of government, and we'd been so fuzzed out by our pop culture around us, that I don't think people really saw this guy for what he was.
It's just funny that Americans have to contend with 2000 channels, and 60 different specific news sources, and the confusion that it creates, and the junk that we get to see is hilarious.
