Election Isn't Over in Arizona

Races still unresolved with 300,000 uncounted ballots to go

PHOENIX—Arizona elections officials continued chipping away at a mountain of uncounted ballots, but a week after the election more than 324,000 uncounted ballots remained, leaving final results up in the air and prompting protests from the Latino community.

At least one high-profile contest remains in the balance: the closely watched congressional race between incumbent Democrat Ron Barber—the chosen successor to former U.S. Rep. Gabrielle Giffords—and Republican Martha McSally. As of Tuesday evening, 829 votes separated the candidates, with Mr. Barber ahead.

Many candidates with large leads—such as Republican U.S. Senate candidate Jeff Flake and Maricopa County Sheriff Joe Arpaio—have declared victory while their opponents conceded.
