The Democratic representative has a 32,640 vote advantage of Republican Congresswoman Martha McSally in the still-uncalled election.

Sinema trailed McSally on election night, but took the lead late last week as the state began counting hundreds of thousands of outstanding ballots. Sinema has expanded her lead each day as new ballots have been counted. Republicans had hoped that later vote tallies would shift and begin to benefit McSally as the state began counting early ballots dropped at polling places on Election Day, rather than late-arriving early votes, which had leaned toward Sinema. But Sinema continued to increase her lead Sunday night.
There are still more than 160,000 votes outstanding in Maricopa County, home to Phoenix and the largest county in the state. Sinema now leads McSally by about 46,000 votes in the county.
“With the latest ballot count, Kyrsten’s lead is insurmountable. McSally’s campaign said today’s results would be her ‘firewall’ but, as we expected, no firewall emerged," Andrew Piatt, Sinema's campaign manager, said in a statement.
Sinema and McSally are vying to replace retiring Republican Sen. Jeff Flake, and either victor would be the first woman to represent Arizona in the Senate. The race was one of the most hotly contested of the cycle, with more than $50 million spent between the two parties and outside groups.
Arizona's vote count moves slowly because roughly three-quarters of the electorate there votes by mail. Every single mail-in ballot goes through a stringent verification process.
