According to the Iowa GOP website, Romney took the eastern and western counties in the state while Huckabee took everything in between. In the Huckabee counties, the pattern was fairly consistent with Huckabee taking first place followed by Romney in second and Thompson a distant third. The counties won by Romney were far less consistent with Huckabee, Paul, McCain, and Thompson frequently swapping places. As the night wanes, Huckabee's lead expands. No other candidate has taken first place in a county, and there are only a few left to report.
I'm having a hard time finding total numbers for the Republicans, but with 1,168 of 1,781 precincts reporting, Huckabee has 25,776 to Romney's 18,925.
According to Fox News it's Huckabee at 38%, Romney at 23%, Thompson at 14%, McCain at 12%.
