What happened over the past four years to cause Burr to change his mind about this judicial nomination? Only one thing. Richard Burr became a mercenary in the War on Obama.
Perhaps part of the reason for the resubmission of the nomination was the recent coming to light of a letter from 2009 (reported by The Huffington Post) in which Burr explicitly endorsed May-Parker for the seat! Apparently, the White House has concluded that Senator Burr cannot maintain such a blatantly disingenuous stance and stonewall the nomination in silence much longer without drawing significant negative attention from North Carolinians.
Good catch, guys.
