Though last night's presidential debate was mostly received as lackluster (and still couldn't outdraw the Palin/Biden vice presidential matchup), there was one bit that caught the eye of many pundits, and it's when John McCain dismissively referred to Barack Obama as "that one." Did McCain forget his opponent's name in a "senior moment," or was he letting his irritable temperament and condescension break through at an inopportune time? Whatever the reason may be, the newly energized Diddy took to his Diddy Blog to rewind the gaffe, and suffice it to say, the Bad Boy impresario is far from pleased. David Letterman , you may have a new foot soldier. [Diddy Blog ]
