Suppose Ron Paul is not willing to compromise on his libertarian principles. Wouldn't he still make a good president considering that there are "checks and balances" and he wouldn't have dictatorial power? I mean there are so many politicians of various denominations out there and none of them that are of any significant power are libertarians - all of them are essentially "compromisers".
Having a diehard libertarian of influence in such an environment can't be bad for the country. Somebody to look after the liberties. To raise hell every time some commercial interests try to impinge on yet another one, you know.
