I would certainly vote for Rand Paul myself, if I could. He seems genuinely commited to localism and limiting bloated government, and just about the only Republican candidate with a sensible foreign policy in my book.

I saw an interview with Lindsey Graham, and despite the fact I despise his foreign policy, he actually came across as very likeable and otherwise sensible. I didn't put him on the list, though, as he is near the bottom of the Republican list at the moment.

Where's Donald Trump!?!? lol

I can understand some of the appeal of Sanders. He does seem to strive against corporate welfare and corruption. Of course, so does Rand Paul, though, without the social democratic leanings of Sanders.

I'm not an American either.

I think Rand Paul has a slightly different foreign policy to his father. I think the son has a more realist foreign policy rather than the doctrinaire non-interventionism of his father. He wouldn't perhaps be as generous or supportive of Israel as some of the other Republican candidates, but he would still support it, I'm sure. And he is less liabe to cause problems in the region that might rebound on Israel, going on the behaviour of the last Republican president.

While it is a tad early to choose a candidate, I would vote for Marco Rubio because of his interventionist stance on foreign policy. I prefer that to Rand Paul's non-interventionist stance. 

I am glad that no one has, so far, voted for Hillary Clinton. She has been art of too many scandals,  leaving her untrustworthy to my eyes. I find her too corrupt.
