PHOENIX – Latest polling numbers released from the Secretary of State’s office shows Kyrsten Sinema has taken a slight lead over Martha McSally in the race for Arizona Senate.

As of 5:30 p.m. Thursday, Sinema has 916,458 votes statewide, while McSally has 914,481.

345,000 votes remain uncounted in Maricopa County while a small number of ballots remain uncounted as well in smaller counties.

Officials estimate about 195,000 of those are early ballots, provisional, and out-of-precinct ballots that voters cast or dropped off on Election Day.

…As preliminary results started to come in Tuesday evening, the two appeared to be in a dead heat with both flip-flopping for the lead.

Maricopa County Recorder Adrian Fontes expects ballot counting to continue for several days. Officials will continue to update the results daily at 5 p.m.
