When Libertarians stay home or vote 3rd party instead of cheerfully supporting the quasi-socialist Republican you have no right to complain then.
I'm actually not too worried about that. Since the inception of the Libertarian Party in 1970, the highest percentage that the LP has gotten in any presidential election was in 1980 - the year that Reagan thrashed Carter. What this all tells me is that the GOP doesn't need to pander to the hardcore libertarians. They just need to stick with the conservative principles of the Reagan/Limbaugh revolution. If the GOP nominates a solid individual who is conservative on both social and economic issues, then the GOP will actually have an excellent shot at winning in 2008 (especially if Hillary - of whom 50% of pollees say consistently that they will not vote for - heads up the Dim ticket).
