Rick Perry’s presidential campaign kicked off with “a lot of hoopla” but has foundered because the Texas governor “wasn’t deep on any of the issues,” says former presidential contender and Godfather’s Pizza CEO Herman Cain.

“He started out with a lot of hoopla, and it wasn’t deserved, because the media, as well as the establishment, wanted to make him a foregone superstar as soon as he got in the race,” Cain told Fox Business Network’s Don Imus Wednesday morning. “And he had to debate. People found out that he had very weak debating skills, in my opinion. He wasn’t deep on any of the issues, and this sort of thing.”

“You’re being kind,” Imus said.

”You know, I’m trying to be respectful,” Cain responded.

Cain suspended his campaign last month amid allegations of sexual harassment and a 13-year affair. His bid was also dealt a blow by a series of gaffes that brought attention to his lack of experience on foreign policy and other issues; among his campaign-trail stumbles, he appeared at a loss when asked by the Milwaukee Journal Sentinel to critique President Obama’s Libya policy.
