I'm surprised, I expected the conservatives to be more economy focused(ie voting for the libertarian) and liberals to be more socially focused(ie. voting for libertarian)... given the stereotypes about young intellectual Republicans being socially liberal and young intellectual Democrats being latte liberals.
But the poll shows the exact opposite.
Only three conservatives have voted so far (me being one of them and it ought to surprise no one how I voted), so you might very well end up with the result that conservatives prefer libertarians. It might just be the case that economic policy matters more to most people.
