Do everybody a favor and nominate Ron Paul for President. I may not subscribe to the same level of economic libertarianism as Mr. Paul, but I have to admire a man with such a fervor for freedom.
Do I think he has a chance? No. The religious right of the Republican party exerts an amazing amount of influence. Mr. Paul is also a civil libertarian. Oops. Somebody forgot to tell him that's not allowed. Apart from gun rights and the right to indoctrinate (implied), modern "conservatives" have no place for such a thing as civil liberty.
If the Democrats were to nominate a Clinton or Obama, Republicans could offer a Ron Paul to America as a welcome alternative. I would vote for him.
Just do it, don't make me beg.
