I don't really follow enough politicians closely in order to know whom I think would make the best libertarian leaning presidential candidate.
I've heard a lot of libertarians saying good things about Justin Amash, the current Chairman of the House Liberty Caucus, but he'll probably want to wait a few election cycles and gain more experience before running for the highest office. He just turned 33 years old last week, and so would barely meet the minimum age requirement in 2016. In the unlikely scenario that he actually manages to be elected then, he would be the youngest president in US history. He is also an Arab, of Palestinian descent, just in case being so young is not weird enough for mainstream Republicans. (He and his family are definitely not Muslims though, but Eastern Orthodox Christians.)
I don't think Amash would run against Rand Paul. That would be counterproductive.
I think Rand is the best option we've got. I know he's not perfect, but a start is a start, isn't it?
