Key federal, state and local primary races remained undecided in the latest Maricopa County vote update Thursday, with some competitors switching places as ballot counting continued.
The Maricopa County Recorder’s Office on Thursday tallied 48,745 early-voting ballots that were dropped off at polling places on election day or arrived by mail too late to be counted before Tuesday. That leaves about 35,000 early ballots and about 3,000 provisional ballots left to be counted.
