With nine days until the election, Democratic U.S. Senate candidate Kyrsten Sinema, urged her campaign volunteers and supporters to increase canvassing efforts.

"We have a lot of work left to do. Early voting is underway and the last day for folks to fill out their ballot and drop it in the mail is this Wednesday," Sinema said to her supporters at an event at her Glendale office.

Sinema, the U.S. representative for the 9th Congressional District, is in a neck-and-neck race with Republican Martha McSally, who represents the 2nd Congressional District in Congress.

A poll released Sunday by CBS News shows Sinema with a three-point advantage over McSally.

Sinema's low-key events in the lead-up to Election Day have contrasted with McSally's rallies and events led by major out-of-state Republicans.

McSally brought in big-name Republicans, including both President Donald Trump and Vice President Mike Pence, in the past two weeks. The events have underscored the national interest in Arizona's Senate match-up, which has seen many millions in spending from outside groups.

While Sinema has not had major Democratic figures visit her in recent weeks, she has had former President Barack Obama and former Vice President Joe Biden endorse her.

As McSally brought in national Republican figures, Sinema has been focused more on volunteer and community events. While Trump was in town, Sinema spent time with veterans at a food bank.

Sinema has struck a centrist tone throughout her Senate campaign and is hoping to win Arizona voters regardless of their registered political party.

"Folks who know me know I don’t care if someone is a Democrat, a Republican, an Independent," Sinema said in an interview with The Arizona Republic. "And here with us volunteering, we have folks of both a political party and no political party. So our campaign is powered on Arizonans' interest, not partisans' interest."
