I wasn't going to speculate other than doubting it was a middle aged middle class white excessive-television-watching couch potato.

My guess is that it is a young male of low socioeconomic status, rural or urban and rarely suburban (due to economics), and of no particular race.

The importance of that, if true, is that Charlton Heston and his caricatured followers (middle aged middle class white guys with guns at home or at the gun range) would be quite irrelevant to policy making, even though they stay in the eye of the storm. In other words, Heston, like Dick Clark, was possibly part of the notoriety calculation, rather than being included for either substance or credibility.
