Regardless of the constitution, I wouldn't be surprised if he pulled a Vladimir Putin, and get on the Democrats ticket as Vice President. I would actually be a simple ruse...when people protest, all they have to say is that the speaker will step up, and benefit from Obama's guidence. We all know Obama would step in regardless of the constitution anyway.
I'm not much of a tinfoil hat type, but to me this is a very likely scenerio.
