The first thing that came to my mind is that our President-Elect really has a lot more urgent things to work on right now (President-Elect Obama, I still love that term).
But the more I thought about it (and granted, maybe this is the vicodin speaking) the more I think that Barack is following that old Klingon adage "Revenge is a dish best served cold."
Let Joe think he's safe, let him think he's bluffed the Dems into submission and then without warning, boom, suddenly he's persona non grata, maybe while on a fact finding trip to Crab Key or maybe Spider Skull Island, or somewhere the US doesn't even have a postal drop box, much less an embassy or consulate. Oh and if his passport just happened to vanish at the same time ...
Priceless, simply priceless.
Barack is being compared to JFK and I think that we need to remember my favorite Kennedy quote "Don't get mad, Get even."
