I cannot say what the Rove/Bush/Norquist intentions are, but they couldn't destroy the Republican party faster if they tried.
It really has been an amazing thing to watch. According to the RNC, donations are still flowing in, yet every single conservative I know has shut down donations for the past year or longer. Either they're lying, or the wealthy, silk sock, country-club, go along to get along crowd of compromisers (e.g., the New Majority pecksniffs), is making up the difference. But something doesn 't compute.
