Tough call, but 20RP12 because at least his social policy mirrors Obama's (I think).

You're a social liberal, aren't you?
Libertarian.
You do understand that means you're socially liberal?
Not technically the same thing. Social libertarians and social liberals usually disagree on a number of issues, eg gun rights/control, hate crimes, preference for issues to be solved a federal vs. state level (ie gay marriage often, abortion sometimes), affirmative action, addressing global warming/climate change, etc. They come from different places philosophically as well, to the extent that social liberalism has a philosophy, that is.
