Joe Biden was picked by Obama to run as his VP in August, 2008 shortly after Obama had returned from his pre-election victory tour of Europe. It was clear that the ticket needed someone with some foreign policy credentials and Biden, who was Chairman of the Senate Foreign Affairs Committee, fit the bill.
Biden is missing the gene that says "Just because it comes into your head, doesn't mean it has to come out of your mouth."
Just the other day Biden, as President of the Senate, was swearing in newly-elected Mark Kirk of Illinois.
Biden instructed Kirk to put his right hand on the bible, leaving Kirk's left hand to be raised to take the oath which is the opposite of the custom in this universe of raising one's right hand when taking an oath.
Sarah Palin might not know her North Korea from her South; but I suspect she knows her right hand from her left.
All of this does not portend a positive future in the White House for Mr. Biden. It means to me that at this very fragile time in Obama's political career, the President has no confidence that his VP can be trusted not to say something which would do enormous damage in Obama's attempt to build a relationship with his former colleagues.
Don't believe me? It was announced yesterday afternoon that Biden will go to New York later this month to "chair a high-level UN Security Council meeting on Iraq." The meeting will be held on December 15, just about the time everyone in Washington will be hunkering down for the final sprint to adjournment.
