Conservative
in the sense of keeping things the same?
Or conservative
in the sense of returning to founding principles?
If the latter, then a non-negligible bloc of people in congress ascribing to the theory that government shouldn't use force except when absolutely necessary (e.g. invasion) would be far, far closer to the founders vision than either the Republican or Democratic party. (If you don't believe me, then please explain the 9th and 10th Amendments, in light of the preamble of the Bill of Rights, without destroying such extraconstitutional activities as the War on Drugs.)
In other words, you ought to explain how libertarians (in federal government) would be of equal or greater "badness" as the current parties WRT the Constitution.
Conservative in the sense of freerepublic.com. a conservative, social conservative, God fearing, political site.
