Democratic Rep. Ron Barber has defeated Republican Martha McSally in the over-time ballot counting for Arizona’s 2nd District, according to The Associated Press.

She is set to hold a news conference Saturday in Tucson.

Barber led McSally by 1,400 votes at the time The Associated Press called the race.

The close margin surprised many in Arizona politics. National Republicans have been quick to credit McSally for making the race so competitive. Still, it was just not enough.

Redistricting improved the district slightly for Democrats but it will likely be a competitive seat for the lifetime of the state’s new congressional map.
