U.S. Senate candidate Kyrsten Sinema’s campaign office released a statement saying she will win the race.

The race for the U.S. Senate between Republican Martha McSally and Democrat Kyrsten Sinema has been close and highly contested. Sinema now has about a 1.5 percent lead according to the Arizona Secretary of State.

Sinema’s campaign manager, Andrew Piatt, said in a statement Sunday night that "Kyrsten’s lead is insurmountable. McSally’s campaign said today’s results would be her ‘firewall’ but as we expected, no firewall emerged."

The statement went on to say that McSally would have to win the remainder of Maricopa County ballots by 22 percent to take the lead in this race, which is "not plausible."
