We have several "conservatives" freepers who actually insist Bob Barr and Jesse Helms are too liberal for them, but a guy like Sen. Zell Miller (conservative rating = 60% = Olympia Snowe) is a great principled conservative who they would vote for in a heartbeat.
I guess according to their standard, Democrats are ALLOWED to be unpredictable, flip-flopping "moderates", but EVERY Republican has to vote EXACTLY like Ron Paul or he's not worthy of their (or anyone else's) support. In order words, Republicans must think EXACTLY LIKE THEM to qualify for office. This from the types who lecture everyone about "liberty" and "freedom". Yeah, a congress where all 435 members are Ron Paul CLONES because otherwise they'd be voted out. Sounds free to me.
But given the way they hold Democrats in HIGHER esteem and to much EASIER standards, it's pretty obvious as to which party these guys are members of. Many of them have even admitted it.
As for holding candidates, regardless of party, to the SAME standard of smaller government, that's fine with me if you want to. By that standard, our nominee for the U.S. Senate (and the previous two for that matter) here in "liberal" Illinois makes him far better than the Liddy Doles, John Warners, and Thad Cochrane's running for office in states with these "hoiler-than-thou" types who always scream how great their state is. His website is down because it's undergoing a facelift but I have a copy of his platform right here. See for yourself:
