Fred has avoided media coverage like the plague. As it turns out, he campaign staff (his wife and Spencer Abraham) were turning down interview requests (including friendly media) without his knowledge.
Other candidates have been on top of the media, such as Romney and Giuliani, Fred has hidden from it. That’s why they’ve been on top, and he’s only gone down since he entered the race. An single appearance on Leno does not make an entire campaign.
We must observe two different media.
