Rep. Kyrsten Sinema has widened her lead over Rep. Martha McSally as the ballot totaling process in the Arizona Senate race stretches into its second week.

The Democrat’s lead stands at about 33,000 votes, according to the latest vote count.

Sinema campaign manager Andrew Piatt called the lead “insurmountable.” Piatt said McSally would have to win the remainder of uncounted ballots in Maricopa County by a 22 percent margin to make up for lost ground.

“This is not plausible,” he said. “Kyrsten will be declared the next U.S. Senator from Arizona.”

While McSally appeared to be the favorite on Election Day, Sinema outpaced her late Thursday and has remained ahead.
