As an outsider who lives in Canada and has absolutely no say in your politics, please keep Obama. Why? Because it's so much more entertaining to watch Republicans get mad at Democrats in power than the other way around. Sarah Palin, Michele Bachmann and Rick Santorum make me laugh and enjoy American politics more than Obama or John Kerry ever could. Extra points go to Bill Clinton, but still.
Also I don't want to see America take steps backwards in terms of human rights. SANTORUM 2012!
