Republican Rep. Martha McSally has raised more than $800,000 in the last three months, more than three times the amount the two Democrats challenging her in Congressional District 2 raised.
The retired Air Force colonel leads in the three-person CD2 race when it comes to raising campaign money.
Filings with the Federal Election Commission show McSally has a $1.6 million campaign war chest.
By comparison, her would-be Democratic rivals, state Rep. Victoria Steele and Former state representative Matt Heinz, had less than $210,000 in the bank combined, the filings show.
Supporters of the first-term Republican kicked in $693,098 during the most recent three-month reporting period, with political action committees adding another $101,500 to McSallyโs campaign fund.
The campaign spent $563,777 during the same period, with roughly half of those expenses related to printing and mailing.
Heinz, who works as an emergency room physician and ran for Congress in 2012, received nearly $204,000 in donations.
Steele received $55,600 in donations during the same three-month period.
Both benefited from donations through the ActBlue fundraising site, a political action committee that helps Democrats raise money through individual donations.
Last year, McSally beat the Democratic incumbent, Ron Barber, by 167 votes in the highly competitive district.
Congressional District 1
In what is shaping up to be a five-way Republican primary in Congressional District 1, rancher Gary Kiehne raised $129,920 for his second attempt at the Congressional seat.
The figure includes a $45,000 loan and more than $16,000 in donations from Kiehne himself. The wealthy rancher has $579,650 left at the end of the reporting period.
Former Arizona Secretary of State Ken Bennett raised $111,530 and had $113,015 left at the end of the reporting period.
Three other Republicans who have recently entered the race, Pinal County Sheriff Paul Babeu, Arizona Speaker of the House David Gowan and businessman Shawn Redd, have not filed any campaign finance-related activity.
Both Babeu and Gowan announced their candidacies earlier this month, after the deadline for the most recent reporting period.
Former state representative Tom OโHalleran, a Democrat, raised $120,156 during the three-month period. He has nearly $109,000 left.
Miguel Olivas, a Democrat, filed his statement of candidacy in August. He has not filed any campaign-related activity.
Congressional District 3
In Congressional District 3, incumbent Democrat Raรบl Grijalva raised $57,000 in donations, with $19,596 coming in from individual donations and $37,500 in donations from political action committees.
Grijalva has about $45,000 on hand. There currently is no Republican challenger.
