Businessman and philanthropist Steve Moak has been on the defense this week after political rival Ben Quayle claimed in a flyer that Moak used his nonprofit charity to make millions for his former company.

U.S. Sen. John McCain will host a fundraiser for ex-staffer Jim Waring, giving the former lawmaker a cash infusion as he heads into the final week of his primary campaign.

Businessman Steve Moak is challenging attorney Ben Quayle's financial dominance in the Republican race in Arizona's 3rd Congressional District.

“It’s virtually impossible to do.” – Republican Steve May, who is running as a write-in candidate for the House in District 17.

Ben Quayle now admits that in 2007 he used a pseudonym to contribute to the voyeuristic website, DirtyScottsdale.com, which later became TheDirty.com, after first denying any affiliation with the site.

Gordon James, who is working for the Quayle campaign, said Quayle contributed to the site under a pseudonym. James would not say which pseudonym Quayle used, but did not rule out that Quayle had contributed to the site under the name “Brock Landers,” a fictional character in the movie Boogie Nights.

Republican congressional candidate Ben Quayle has issued a stinging rebuke to rival Vernon Parker for his statement that Quayle "rented a family" in campaign mailers that depict him with two young girls. Quayle called Parker a "flawed" candidate and took a shot of his own in a press statement, dredging up a 2008 U.S. Small Business Administration investigation that alleged Parker falsified documents to obtain a $1.2 million federal government contract for his consulting business.

Two recent mailers sent by the Ben Quayle campaign contain some curious images and statements by the 33-year-old lawyer and flush-with-cash candidate in Arizona's crowded 3rd Congressional District primary.

Attorney Ben Quayle, who is seeking the Republican nomination in the 10-way contest in Arizona’s 3rd Congressional District, has raised a whopping $1.1 million for his campaign.

Ben Quayle is a political neophyte who has spent a small fraction of his life in Arizona, and he lacks the kind of business experience or community involvement that usually precedes a run for Congress. But what Quayle does have — a ton of money and his father’s last name — scares the bejeepers out of the nine other candidates seeking the Republican nomination in Arizona’s 3rd Congressional District.
