Days before Tuesday's Arizona primary, one of Ben Quayle's nine Republican opponents is on the air, hammering him for his connections to the bawdy, sex-themed website, TheDirty.com.

"News reports link Ben Quayle to a raunchy website that degrades women," the ad, paid for by Scottsdale businessman Steve Moak, says as graphics from TheDirty.com float in the background. The ad began airing Thursday night.
