I'm one of the few people who when taking the political compass quiz doesn't get right-authoritarian or left-libertarian. I always get right-libertarian. However, over the years I've stopped worshiping Ayn Rand and anarcho-capitalists and have become much more closer to the center. The last two Presidential elections I voted for the Libertarians, and during the 2016 Republican Primary I voted for John Kasich. I don't think I could ever vote for a Libertarian again due to what they actually stand for. Yes, their Wikipedia page says they support "classical liberalism" but in reality they are mostly composed of anarchists. They're completely out of touch with society and frankly reality as a whole.
I consider myself a never-Trumper and will never vote for him, and during the next election cycle I plan on voting for Chris Christie, who to me seems like the most genuine of all the candidates that are in the field. But if anyone but Trump wins the Republican nomination I will vote for him. If Trump still manages to win the nomination, probably in jail at that point, I'll vote for the Reform candidate. If the Reform candidate isn't on the ballet of Wisconsin maybe at that point I won't vote for President at all.
However, one thing I do know is that I'm never supporting the Libertarian Party ever again. I still get newsletters from them saying "defund the government" but they still beg for donations themselves and they wonder why nobody ever supports them...
