Quick Thoughts...

...hammer the message home in the media: install Rush as the Pope of the Republican Party.
...count on Rush relishing this and continuing to press his advantage as Repub politico after politico slips up, says something non-canon, and has to kiss Rush's oxycontin-dusted ring.
...count on the moderates being absolutely sick of this and edging closer to the Democrats as a result.
...pick up extra seats in 2010 as the Repubs have retreated further into the echo hall of chamber mirrors.

But what don't they count on?

I still say the moderates join the Dems, as is planned. The Repubs continue to become a regionalized party geared toward disaffected whites and the rich. Fine. But the moderates won't like the Left wing of the Dem party too terribly much either. They form like Voltron with the more middlish Dems... split before you know it.

...and America has three parties in a two-party system. Then the fun begins.
