The magic number of delegates needed to claim the Democratic nomination used to be 2,025, and the Barack Obama campaign says it still is.
But rival Hillary Clinton's campaign has been arguing recently that the finish line should be 2,209 -- a figure that includes the uncounted delegates from Florida and Michigan. (Yesterday's Democratic congressional pick-up in Mississippi brings Clinton's new magic number to 2,210.)
Asked to explain the changing goalposts, Clinton spokesman Howard Wolfson pointed to the appeals filed by Florida and Michigan with the Democratic National Committee. A hearing is scheduled for May 31.
"We're on the side of maximum participation,'' Wolfson told reporters in a telephone call. "We're on the side of letting every vote count."
In fact, Florida's appeal asks for only half of the state's delegates to be seated at the nominating convention.
