You're right - it doesn't exist. Rush was one of the main reasons Bush won the nomination over McCrazy, and for that I am eternally grateful. He will also oppose him in the '08 primaries.
However, that has nothing to do with the point I made, and I think you know it.
If, somehow, McCain is the GOP nominee for President in 2008, Rush and the rest of the GOP-first types will support him without reservation - simply because he is the LOTE with the Beast.
Personally, I'm voting straight ticket Pubbie this year, because there are still two more years to enact conservative legislation.
I believe McCain will be shoved down our throats in '08 - in the view of the GOP party people, it is his turn (like Dole in '96).
For the record - I will never, ever, under any circumstances, vote for McCain - regardless of how much invective the GOP kool-aid drinkers spew.
