Yep, vote for the real conservatives, they need our support and it sends a message that they can and should win and stand by their principles.
Maybe in some congressional districts and a few of the smaller populated states, but a principled real conservative stands little chance in a national election. Reagan and Bush are the closest we can get, like it or not. Reagan was about as much of a compromiser as Bush, although Reagan was far superior in voicing true conservative views.
