(CNN) -- Sen. Barack Obama decisively defeated Sen. Hillary Clinton in North Carolina Tuesday, but Clinton's narrow victory in Indiana will likely send the race for the Democratic presidential nomination on to the next round of primaries. Sen. Barack Obama and his wife, Michelle, greet supporters in Raleigh, North Carolina. As polls closed in Indiana, Clinton had a double-digit lead over Obama, but by the end of the evening, Clinton's lead had shrunk, dragging the race out until early Wednesday. A clear winner did not emerge until 1:15 a.m. Wednesday -- seven hours after the polls closed -- because results were slow to come in from Lake County, a Chicago suburb in northwestern Indiana with several precincts that went strongly for Obama.
