It apparently took a call to roust a precinct chair out of bed to confirm results that finally, at 2:33 a.m., gave Mitt Romney a victory, by 8 votes, in the state of Iowa. State Republican officials said that, with 99 percent of the precincts counted and with Romney within four votes of Rick Santorum (29,968 to 29,964), they could not declare a winner until one precinct from Clinton County, in eastern Iowa, reported its results.
