Oops, he did it again.

For the second time in as many days, Sen. John McCain (R-AZ) has confused President Barack Obama with another person during a campaign event for Republican presidential candidate Mitt Romney.

On Thursday, the Arizona senator had declared that "President Obama will turn this country around," and was quickly corrected by both Romney and South Carolina Gov. Nikki Haley.

Less than 24 hours later, McCain was on the stump in Conway when he goofed again.

"He will rebuild the moral of American and he will restore America," McCain said of Romney. "I guarantee you he will not lead from behind like Ronald Reagan. He will lead from in front."

Both Romney's wife, Ann, and Haley turned to look at the candidate, but he simply applauded this time instead of correcting the 2008 GOP nominee.

McCain most likely mangled a line that he had used several days before in New Hampshire.

"I guarantee one thing," McCain declared. "No one will ever say that Mitt Romney will lead from behind. He will lead from the front like Ronald Reagan did."

Republicans have long mocked President Barack Obama over the assertion that he was "leading from behind."
