I'm confused. First you say the Conservatives need to lose in 2006 to win in 2008. Then you say that you're talking about Conservatives, not Republicans. Last time I checked, there is a Conservative Party out there (at least in a few states), but to my knowledge Conservatives hold no (as in zero) US House or Senate seats. Since the alleged Democrat conservatives (of which there are a few), are not likely to band together with alleged Republicans conservatives (of which there are a few more), I don't see how Conservatives or conservatism are going to benefit by a
Republican defeat in 2006. If such a
coup d'etat were possible, it would create a clear Liberal Democrat Party plurality (which would equal a majority in Congress), leave a rump "moderate" Republican Party, and a (Congressional) minority Conservative Party that would find it practically impossible to form a coalition with (or even work with) one of the two larger political parties: in part because to compromise would be to do exactly that of which conservative critics accuse the Republicans, "compromising and selling out our principles", and in equal measure because both the Republicans (particularly) and the Democrats (generally) would be so upset about their defectors to the Conservatives that they would be in no mood to grant the Conservatives any voice in the affairs of government.
I also think that you grossly underestimate the amount of time it would take the new "Conservative" Republican Party to a. recognize its mistakes, and b. to "turn things around" with the American people. After the 1964 election debacle with the Goldwater Conservatives, it took 16 years for a Conservative Rennaissance (under President Reagan). After Mr. Reagan's former Vice President abandoned, and was abandoned by, conservatives, it took eight years of Bill Clinton to set things right. Once the Democrats regain control of Congress, the entire "mainstream" news and entertainment community will invest all their energy into convincing the Sheeple of America that they never had it so good. It would be criminally naive to think that you could turn that situation around in two years (even if two years were a "lifetime in politics).
