Howard Dean isn't that far off here: there are groups on the fringes of both sides that disdain certain people groups. That is, in essence, why they are fringe groups and extremists. The question here, then, is why Dean feels the need to talk about such groups in a serious discussion of politics. But the fact is, last night he did just that with Lawrence O'Donnell:
The answer seems to be that Dean doesn't really want to talk about the fringe groups to talk about fringe groups. He wants to talk about them in order to lump the normal right into such groups. It's a political and rhetorical tactic. And unfortunately, it's one that works a lot of times.
