The only way he can generate buzz is to pick a fight with people who actually have an audience. Rush doesn't fall for this crap anymore after Franken wrote his book. B.O.R. learned to ignore him, just as the rest of the cable audience seems to be doing.
Yep, Rush completely ignored Franken's book, and the book ended up on Wal-Mart's discount bin.
Savage (The Weiner Nation) has to do the same. He keeps escalating his attacks in frustration since they ignore him and won't take the bait.
