The Constitution Is Unenforceable
Read
this piece at Ace of Spades HQ about how nobody can make Obama prove he's an American citizen and thus eligible for the presidency and about how no one seems to care that Hillary Clinton is textually barred from serving as Secretary of State (because she, as a legislator, voted to increase pay for that position).
Once the incoming administration has finished rendering those obscure bits of the Constitution obsolete, wait until they get into the choice bits. If we're going to start the pool, I think they'll nullify portions of the first amendment first, because if they reinstate the Fairness Doctrine or otherwise impede freedom of the press, religion, and assembly, they won't trigger an uprising.
