Boosted by a new ABC/Washington Post showing him now in second place the GOP presidential race, Herman Cain spent Tuesday morning attacking former Mass. Gov. Mitt Romney, rather than the prior top target, Texas Gov. Rick Perry.

Appearing on Fox & Friends to also promote his new book This is Herman Cain, the former CEO of Godfather's Pizza labeled Romney as too "Wall Street" for voters and took another swipe at the former Massachusetts governor's health care law.

"He's not going to be able to shake the ankle breaks as I call it, of RomneyCare," he said. "It's going to continue to haunt him."

"His business experience is Wall Street, mine has been main street," he said. "I've actually run individual units. I've actually made the pizza. I've actually cooked the burgers. I've actually clean the toilets. I've actually run a bunch of small businesses. My experience is more main street than Wall Street. I have a lot of respect for him, we're just different in that regard."

Cain also discussed Perry's poor performances in the debates so far.

"The debates are not as easy as some people may think," he said. "And I think that he probably underestimated how prepared you need to be for these debates. Remember you only have a minute to answer the question, sometimes you have to think very quickly. So he was not prepared for that format."

Based on the ABC/WaPo, Cain is now in second place with 16 percent, tying Perry. The poll also found that Romney is the new frontrunner, drawing 25 percent support.
