Nearly a week after all the ballots were cast, Democrat Kyrsten Sinema has been declared the winner in Congressional District 9.
After counting ballots all weekend, Sinema has nearly 6,000 more votes than her Republican challenger Vernon Parker. Parker called her to concede Monday afternoon.
We spoke with the congresswoman-elect.
Sinema is New York and was on the plane when the race was called. She tweeted that she had 80 congratulatory text messages when she landed.
After a week of waiting, both candidates were ready to finish what became one of the most contentious and costly campaigns in the state.
Kyrsten Sinema resigned from the State Senate to run in District 9. She knew it wouldn't be an easy win.
"There was one where our team knocked on over 13,000 doors in one day and we did that for almost an entire year," she says.
After spending 7 years in the Republican controlled Arizona legislature, Sinema says she knows what it takes to reach across the aisle.
"Take a look at my record. I have always been someone who speaks my mind and does what I believe is right. I do what is right for my constituents and I'll do that every single day as a member of congress representing my district."
Former Paradise Valley Mayor Vernon Parker called Sinema to congratulate her.
"I ran for congress not to be called a member of congress. I ran for congress solely because of the future of this country, for a better America for those who are coming behind," says Parker.
With a margin of victory of just 4 percent, Parker believes one candidate may have siphoned votes away from him.
"The libertarian. He grasped probably 6 percent of the vote. Had he not been in the race we would be in congress right now," says Parker. "Obviously I was somewhat disappointed but it is what it is. I really hope the best for the country, for CD 9 and I really hope the best for Kyrsten Sinema.
Sinema will be entering a Republican-controlled house.
"What congress needs is to put aside partisan ideology and solve the problem. It is going to take some hard work and some sacrifice on all our parts."
All added up, $8 million was spent on that race.
One congressional race remains undecided in Arizona's 2nd Congressional District. Ron Barber and Martha McSally are separated by just hundreds of votes.
