It's the game plan in the "Two-Party Cartel". The elites in the pubbie party are ticked at GW. Why, I don't know. He has carried much water for them but just what would happen if we truly had a conservative next cycle. They would be forced to put up true conservative judges to the Supreme Court & if not then all would see this phony cartel. It will be the dems winning in 2008.
I wouldn't mind taking it on the chin for 4 yrs by a Dim if I could play a part in finding & electing TRUE conservatives (Republican OR 3rd party) into Congress or the Presidency (the House of Representatives is especially important here, is even more than the Presidency!).
I think you are looking short term when you worry about our ending up electing a liberal into the White House--& I'm talking long term. I'm talking about building an ever-increasing conservative/constitutionalist movement that could last for decades; & if that means having a liberal as President for 4 yrs, then that's the price we pay; but the benifits we will reap later will far outweigh the knocks we are dealing w/ short term.
