(CNN) - Arizona House candidate Ben Quayle on Friday stood by a statement in a new campaign ad that called President Obama "the worst president in history" but offered nothing more than Republican talking points to back the claim.
Quayle, the son of former Vice President Dan Quayle, shares his father's conservative values and is one of 10 Republicans vying for the GOP nomination in Arizona's Third House district.
"He's an ideologue from a leftist bend," Quayle told CNN's John King in an interview to air Friday on John King USA. "I think that he's trying to take control of more parts of the private sector. He's trying to make government the answer to all the problems that we face when we should be focusing more on individual responsibility."
"I stand by my comment," he said of the campaign ad.
"The future that he [President Obama] has created for my generation and other generations is pretty terrifying," the 33-year-old candidate said. "It seems like right now he's starting to destroy the American dream."

Quayle did not point to any specific policies, programs, strategies or remarks from the president that supported his comments, however.
Quayle also responded to allegations that he penned regular contributions to a now defunct website called DirtyScottsdale.com. The site has since been renamed theDirty.com, but features similar content – gossip about nightlife in cities around the country. A quick glance at the website offers an endless stream of photographs of provocatively dressed women.
The site's owner, Nik Richie, wrote in an August 9 blog post that Quayle was the person behind the alias 'Brock Landers.' Quayle has admitted to writing several blog posts for the original DirtyScottsdale website, but says he is not behind the Brock Landers posts.
"I posted a few comments on a website that doesn't even exist anymore, they were innocuous and, you know, these are the types of smear campaigns that are being pushed against me about nothing," Quayle told CNN on Friday.
Arizona's Republican primary will be held on August 24.
