Shorter Lanny Davis on the Wall Street Journal editorial page:

I know you think "McCarthyism" refers to the misuse of institutional power against ordinary people, but it actually means the exact opposite. In fact, if there had been blogs with comments sections in the 1950s and people who'd been blacklisted had gone to them and called Joe McCarthy "a dirty mick," that would have been McCarthyism.

UPDATE: Shorter Mark Levin at National Review Online:

Does Lanny Davis really believe a handful of lefty blog comment posters are as bad as Rush Limbaugh and Ann Coulter? That's nuts! They're much worse than Rush and Ann!
