and Libertarians are not conservatives.... but i agree the Contitutional Party seems to be - mostly.
I agree, too, although some Libertarians are conservatives just as you will find some Democrats who are conservatives that have reasons for supporting their party.
The Constitution Party and and the Libertarian party share common ground on the limited role of the federal government in many respects, primarily that the Constitution limits the scope of federal power. In the sense that the Constitution and Libertarian parties both advocate that the restoration of the reserved powers of the states and the people (see Amendments IX and X), both are conservative. I think that hubbubhubbub was referring to their views on limited federal government.
The Republican leadership has proven to be liberal in this regard as they no longer have the excuse of Democrats controlling the Senate, U.S. House, or White House.
You are quite right about the Constitution Party and very wrong about the Libertarian Party. The LP takes a very clear stand against "restoration of the reserved powers of the states." Who ever has fed you this line of crap is either a liar, or is so all ill informed that they are not much better than one.
Starting with just the basics, the very short Libertarian Party Statement of Principles, should be enough to clear up the matter. Where it says "we... deny the right of any government..." it means national, state or local. But if needed, a close examination of the LP platform will more than dispel this notion. The Libertarian Party is not a constitution party of any sort what so ever, nor is it a conservative party.
