The ones liberals talk about the most are the ones who make it to the top.

The outrageousness is just one part of it. Republican spokesmen say outrageous things on purpose, so when they draw a reaction the spokesman can say "See how they hate me?" Ann Coulter is the best at this ever, but it's nothing new, Pat Buchanan and even Wm F. Buckley did it decades ago.

What makes a good Republican pundit is the ability to say things he knows aren't true, but with such conviction that you could believe it if you really wanted to. The idea is that lots of people would rather believe an attractive lie than the less-attractive truth, so you feed them semi-plausible lies and they're happy.
