Corruption in the electorate will be so ingrained by 2016 that Biden will be a walk in. His only threat is a serious contender in the Democratic primaries. Whichever Democrat wins the primaries and gets crowned during the convention will be our next president. It might even be Obama again. Rule of Law will mean nothing, and the Democrat majority in 2014 will fix it so Obama can run without limit. I’d rather have the court jester than the fool king, or the wicked witch.
How does that work? It takes more than Congress to amend the Constitution.
