Well, for being drawn in by the old, lame foes he should know for what they are: The Washington Post, the NY Times and Drudge.
For letting his disappointment over what he considers Bush's failures make him an embittered ranter, no longer fun to listen to.
For pouncing as eagerly on any rumor, leak or slant about a Bush mistake as he ever did on anything about the Clinton's.
For not checking, trusting, waiting to see, but just jumping on Bush with both big feet.
That's some of the what.
That's what he did to X42 and it catipulted him to the top.
Unfortunately, with Prez. Bubba it was usually true and with President Bush it is likely not true.
If the ratings slip, Rush will change. He always has before (like when he spent so much time talking about cigars) and he will again. He is an entertainer, not a pundit, and not an employee of the GOP.
Shalom.
