There was a race on NBC tonight but it wasn’t simply an Olympic one. The network’s Chief White House correspondent Chuck Todd came on air at 9:22 PM PT during the XXX Summer Olympics to announce that NBC News was calling Rep. Paul Ryan as Mitt Romney’s choice of Vice-Presidential candidate for this year’s Presidential race. Coming right in the middle of NBC’s highly coveted primetime Olympic coverage, Todd along with Chief Foreign Affairs Correspondent Andrea Mitchell broke into a track and field relay that was on at the time. As far as can be determined, ABC, CBS and Fox did not break into the episodes of 20/20, CSI:NY and Bones that they were respectively playing.
