Former New York City Mayor Rudy Giuliani (R) threw his support behind Mitt Romney on FOX & Friends Monday saying the former Massachusetts Governor has proven he’s the most effective republican to take on President Obama.

“This is going to be an election about the economy and if I look at all the Republican field and Democratic field, who better than Mitt Romney to carry our banner and to point out this has been a failed economic program and that with sensible, conservative economic principles, this country will have a boom,” said Giuliani. “We’ll grow unlike anything we’ve actually predicted.”

Giuliani also said he wanted to support a candidate with strong foreign policy skills who would stand up for America.

“I think Obama has us down a very dangerous path with Iran, with this pathetic desire to want to negotiate with them,” Giuliani said. “I don’t think you’re going to see that with Mitt Romney.”
