There was no 22nd Amendment when FDR got a 3rd term.
Nobama will have to throw out the Constitution to get any more than 8 years. Not saying he may not try, just saying lots of patriotic Americans will be standing in the way and if somehow he gets around the 22nd, that will give free rein for Texas and other States to ignore the secession restriction and let the libs and their ComeYets eat cake.
Not to mention that Joe Biden wants to run in 2016. And Hillary, though I’m sure she could be Petraeus’ed before then.
