Idk how the LP nomination BS works, but from what I have been hearing it sounds like one of the other candidates gave his votes to Oliver in order to help him win. Alot of the libertarians involved in politics are also just liberteen pieces of shit.
And Rectenwald, despite getting more votes than either of the other two candidates individually, is apparently too much of a pothead to be a decent messenger anyway. The LP is just destined to always be a complete fucking joke. Which is just as well, a consistent application of libertarian principles is completely incompatible with politics.
