There are still hundreds of thousands of votes to be counted in the last one percent of districts (including the very blue Tucson), with many speculating that the victor will not be named for several days.
The suit filed by four county Republican parties - Maricopa, Apache, Navajo and Yuma counties - alleges that the state's 15 county recorders don't follow a uniform standard for allowing voters to adjust problems with their mail-in ballots, and that two counties improperly allow those fixes after Election Day.
The Latest on a lawsuit filed by Arizona Republicans seeking to block some ballots from being counted.
"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", Sinema for Arizona campaign manager Andrew Piatt said in a statement.
Currently, several other counties that lean Republican destroy mail ballots if voters don't help verify their signatures before polls close on Election Day.
Mahoney said it was too soon to require Maricopa and other counties to stop contacting voters to verify signatures on mail ballots. McSally and her GOP allies often tried to use Sinema's past against her, casting her as a far-left politician masquerading as a moderate.
Democratic leaders are vowing to fight back if any of the votes are discounted.
Pirates’ Corey Dickerson Wins First Gold Glove Award
The other two Cubs first basemen to win Gold Gloves: Mark Grace (four times) and Derrek Lee (twice). Kolten Wong was a finalist for the National League's second base gold glove.
A Maricopa County Superior Court judge who heard preliminary arguments on the lawsuit Thursday set a full hearing for Friday afternoon.
Both Sinema (88 percent) and McSally supporters (88 percent) have a high degree of vote certainty, and equal numbers of Democrats (50 percent) and Republicans (50 percent) are extremely interested in the election. "There are a lot of outstanding ballots - especially those mailed-in - and a lot of reasons to feel good!"
The Arizona race would cut into that.
Leonard Aragon is a Democrat and supports Sinema.
Republican Gov. Doug Ducey was easily re-elected over a challenge from Democrat David Garcia, a college education professor. The GOP notched victories in the Attorney General, Treasurer and Secretary of State races as well. That seat is now held by a Democrat.
Five percent are still undecided about their vote in the Senate race. They are battling over the seat vacated by Sen. Jeff Flake, a Republican who decided not to run for re-election because he realized his criticism of President Donald Trump made it impossible for him to survive politically. She has tried to rally Republican voters by emphasizing her military background as the first US female combat pilot while touting her support for the president's tax cut and other parts of his agenda.
The situation could represent a cruel twist of fate for Sinema, who started her own political career running for the Arizona House of Representatives in 2002 as an independent affiliated with the Arizona Green Party.
