This is certainly an indictment of Kristol and the Weekly Standard, but not of conservatism. Anyone who would consider either McCain or Giuliani is no conservative and conceivably has never been one.
Liebermann should be opposed to what happened to him in Connecticut because it was funded by outside-Conn money, by neo-Dems of the MoveOn anti-Defense persuasion.
If Liebermann is going to be the last of the true Democrats to stand for defending his Nation, then so be it. That is an acceptable reason for running against the neo-Dems.
I think a lot of half-@ssed "conservatives" like the folks at the Weekly Standard are p!ssed off at Pat Buchanan because he's done an effective job of exposing these "neo-conservatives" as nothing more than big-government globalists who aren't really conservative at all.
