Election of the former First Lady back to the White House is just like re-electing Bill. That's unconstitutional, and I'm sure if the founding fathers had considered this at the time, they would have put a prohibition to this situation in writing.

I bet from now on the husband wife team will be more prominent in politics. It's an easy way for an insanely popular First Family to get 16 years out of the presidential office. I believe the 8 year limit was imposed for a reason.
