Republicans are more likely to go libertarian than democrats, and with this election in particular, whatever gets people to not vote for trump, I'm all for it. It just means Hillary wins. So you would be making a statement against trump, yet not outright supporting Hillary. I say go for it.
My view of libertarians tho is this: former republicans who have decided they are more accepting of other people's definition of morality and believe strongly in freedom....yet they still don't give a crap about helping people, either internationally or within their own country. I may be a little wrong because I really haven't given them the time of day, despite being a political junkie.
