Most of the outstanding ballots are coming from Arizona's largest county, Maricopa County, which is home to Phoenix and includes Kyrsten Sinema's congressional district. "With half a million ballots left to count, we remain confident that as votes continue to come in from counties across the state, Martha McSally will be elected Arizona's next senator," McSally campaign CEO Jim Bognet said in a statement. “Arizonans must have faith that their votes are counted, and we are working diligently to ensure that count proceeds in a fair, transparent, and timely manner that voters can trust,” Andrew Piatt, Sinema’s campaign manager, said in a statement Thursday afternoon. "We also know that when the Maricopa County Recorder releases its first batch of ballots this evening, there will still be approximately half a million votes left to count," Piatt continued.
