Wow, that was a lot of work.
Some of your post--the part on FDR and Reagan in particular--is as much a comment on leftist mythologies as it is on Rush's.
I'll just comment on one point:
Tom, lemme tell ya, us here on the left side of the fence are delighted to publicize Limbaugh's rantings far and wide. There's no better way to discredit the Right than in their own words.
Odd. Considering the amount of effort being expended on the Left to revive the Fairness Doctrine, or nail Rush on drug charges, I wouldn't come to that same conclusion.
