Akhil Reed Amar, professor of Constitutional Law at Yale Law School, has a fun article in SLATE regarding the possibility of swapping the presidency between Obama and Hillary on the same ticket within the same term (with or without congressional approval). He suggests that this dream team, under ideal circumstances, could remain at the helm until 2016!  Sounds a bit zany to me. More seriously, Article 25 of the US Constitution may have some lessons for close elections in polarized states like Kenya and Bangladesh.
