This may surprise a lot of you, but I liked this guy.
The video above is not a good example of this, but typically, he was cool, calm, and collected when voicing his opinion with conviction and indignation. I admired that he did not bullshit, whatsoever. He appears pretty belligerent in the video posted above, but hey, he's playing to CPAC, so that's to be expected.
I also admired that, where a lot of conservatives won't go on MSNBC or shows like Real Time with Bill Maher, because they claim they don't want to dignify and legitimize them (but, to me, usually appear to be more out of fear that they will be made to look foolish), Breitbart would do these types of shows, guns blazing. And he didn't compromise what he was saying one bit for the liberal studio audience.
Here he is on msnbc, in some appearances that I feel was more characteristic of him.
And I too saw the "natural causes" report. There's nothing natural about a death at 43 in the year 2012.
