How many of us are? I'll bet a very small minority on FR attend meetings or run for/are a delegate in their state GOP. I'd love to be proved wrong, but I don't think I am or the GOP wouldn't be run by weak-kneed towers of jello.
I would surmise that running for office is quite low on most Conservatives' "to do" list as we have all been witness to the personal destruction wrought upon those who stand up and push Conservative ideals. Not only that, but I would wager that most Conservatives absolutely LOATHE the thought of being politicians and actually having to sit in the presence of those same people we despise.
I am going to paraphrase a post from earlier in saying that there are Conservatives who have well-grounded and principled positions which they are willing to promote, and then there are those Conservatives who are meant to lead other Conservatives in the fight. Not all of us yearn to become "political activists" and lead Conservatism, but are ready to follow and support such a leader with immeasurable fervor.
