Arizona Rep. J.D. Hayworth has not yet conceded in his apparent loss to Democrat Harry Mitchell. In fact, there are about 250,000 ballots still to be counted in Maricopa County; only part of that number would be in the 5th District.

This is the current total:

Mitchell: 73,762/51%
Hayworth: 67,830/46%
Severin:4,754/3%

One analyst says that Hayworth would need 80% of the remaining votes (which are less than those above), but commenters on the first link think he'd only need 53%.
