OBAMA: I'm not on the ballot, but -- I've got one more campaign to run....

Well, he can run for Senate in Illinois in 2016 to replace Republican Mark Kirk, or in Hawaii in 2018 to replace Democrat Mazie Hirono. Since it might be a bit unseemly for a sitting President to run for Senate, my money's on a 2018 run from Hawaii.

Of course, there's also the Secretary General of the United Nations. Ban Ki-moon's term ends December 31, 2016. I'm sure they would wait until January 22, 2017....
