but he takes the correct position at the federal level: Leave it up to the states. On virtually every remaining issue, he is genuinely one of the most radical libertarians I have ever encountered, and is probably the most radical libertarian in federal office in the last 100 years. This purity is a big plus for me, as I have trouble voting for someone who would reduce even one person's liberty a minor amount if they were elected. Plus, his knowledge of economics, history, and politics is quite encyclopaedic, and while I am not interested in electing a good technocrat, while there is still a massive federal government in place it would be good to know what you're doing as President. Therefore, I would be happy to vote for him for President.
I honestly do not understand why pro-lifers would refuse to vote for a pro-choice libertarian. Simply implementing every other libertarian issue would clearly create an environment where the incidence of abortion was severely reduced. I will not go into the details here of why I think this. If reduction of the number of abortions performed was a more important goal to you than seeing to it that women and their doctors are punished severely, it seems to me you should vote for the pro-choice libertarian.
