Former Massachusetts Gov. Mitt Romney (R) said Friday that Democratic presidential candidate Barack Obama is “extraordinarily naïve” on foreign policy and the economy and predicted that the Illinois senator’s “sweet talk” would lose out to Sen. John McCain’s (R-Ariz.) “straight talk” in November.

In the general election, Romney said, “people are going to focus on Sen. McCain, his vision for our economy, his vision for foreign policy, his years of experience, as opposed to somebody, Barack Obama, [who is] well-spoken, but extraordinarily naive, particularly as it comes to both.”

Romney also said that he has not had any open and frank discussions with McCain about sharing the GOP ticket.

“I’m not going to get into the process that he’s going through,” Romney, McCain’s rival in the Republican primaries, said with regard to the vice presidential search process. However, when asked on NBC’s “Today Show” whether he had had such discussions with the presumptive nominee, Romney replied: “I sure haven’t.”

The former governor has been an important surrogate on the campaign trail and is widely seen as one of the favorites to be on the GOP ticket.

On Friday, he blasted Obama for going on a “campaign swing” in Europe and the Middle East instead of a “fact-finding” mission that would help him develop his policy.

Romney predicted that Obama would be “warmly received” in Iraq.

“People of different political backgrounds are warmly received there,” he added.
