Because conservatives are hypocrites. They sat on their asses waiting for Fred! to arrive on his white horse when the real Reagan Republican was already in the race.
Also Hunter has ran an obsolete campaign. He's got to have a strong message that reasonates across the board like Paul does. Hunter opposes gambling, for crying out loud. How the Hell is that supposed to get you support?
If Hunter's campaign is "obsolete," it's only in the sense that modern American society has become so decadent that a man of virtue, honor, and decency is considered passe. It's tragic that so many people, even on FR, are following the "horse race" between unprincipled egotists like Rudy, Romney, etc., rather than getting behind the real conservative, Hunter.
