WASHINGTON (CBSDC/AP) — Former GOP presidential candidate Mitt Romney says there is no question in his mind that he would have been more effective in the White House than President Barack Obama. But he reiterates he has no plans to run again.

My time has come and gone, Romney told Fox News Sunday.

Romney cited continuing high U.S. unemployment and growing troubles abroad, and that some of those who voted for Obama might now have some buyer’s remorse.

Yet he said he didn’t want to dwell on the past, while admitting he had made mistakes in his campaign — and that the Obama campaign did a good job on picking up on them.

Romney stated that he would make a better president than former Secretary of State Hillary Clinton.

“No question about that, in my mind,” Romney told Fox News. “The American people may disagree with me. You’ve got to get this economy going. You have to have people who understand what it takes to create jobs and to help people come out of poverty, to help the middle class have a better and more prosperous future. You’ve got to have that understanding.”

Romney added that Clinton does not have the experience to run a government.

“Hillary Clinton and Barack Obama are two peas in the same pod,” Romney said.

The former Massachusetts governor also reiterated he has no plans on running for president for a third time in 2016.

Romney said, “I’m not running and not planning on running.”
