Nate Silver at 538 asks: Did talk radio kill Conservatism?

I just read a fascinating piece I came across via Crooks and Liars. David Neiwert (Orcinus) highlighted this piece by Nate Silver over at 538:
538: Did-talk-radio-kill-conservatism?

This really grabbed me right here:

There are a certain segment of conservatives who literally cannot believe that anybody would see the world differently than the way they do. They have not just forgotten how to persuade; they have forgotten about the necessity of persuasion.

So true.
