OK, and when was the Republican Party actually conservative? Since circa the 1960s they are more conservative then the Democrats but that's all. At least there are fewer liberal Republicans these days and even major RINOs like Chafee, Snowe, Collins and Specter are more conservative then the old Rockefeller Republicans (like Percy, Brooke, Javits or Rockefeller himself).
So, it is long past tiem for conservatives to take the respendican party to the wood shed. If that mean withholding support and letting a few go down in flames as an example to the rest so be it. Socialism fast or socialism slow what is the big difference.
Today, the Republicans are the same as the Dem's were, decades ago...moderates mostly. Bush is a moderate.
Today, the Democrats resemble most closely, the Reds.
