Republicans filed a lawsuit Wednesday night after a "too close to call" election's early results put Republican candidate Martha McSally -- with 49.45 of the votes -- ahead of Democratic contender Kyrsten Sinema, who has 48.4 percent.
Republicans don't want the mail-in votes included and they are asserting there is no system in place to ensure verification of voter identities.
As reported by the Associated Press, About 75 percent of Arizona voters cast ballots by mail. A large part of the mail-in ballots are potential Native voters. Currently there are more than 600,000 outstanding votes in the AZ U.S. Senate race.
Republican Rep. Martha McSally and Democratic Rep. Kyrsten Sinema were separated by only 17,000 of the 1.7 million votes. Some say if the votes are allowed, Sinema will win, if they are disallowed, McSally will win.
As additionally reported by the AP, a suit by "Four county Republican parties 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 lawsuit is scheduled to be heard Friday, after the next release late Thursday of tallied ballots."
The tabulation process is expected to take several days.
