Mitt Romney Often Wonders Why He Stayed Out of 2016 Presidential Race

"I ask myself that a lot," he said.

"I get asked on a regular basis, 'Boy, why aren't you running this year?' I ask myself that a lot too. But I did that once," Romney said.

He laughed about how much fun he had running in the 2012 race, encouraging the audience at an event hosted by the U.S. Chamber of Commerce, "If you get the chance to run for president, do it."

Romney also assailed both candidates for failing to pay attention to policy issues affecting Americans.

Trump has met Romney's criticism this cycle with a blistering critique of his own, accusing the former Massachusetts governor of "choking" in his contest against Obama.

The question now is whether Trump will lose by a bigger margin to Clinton than Romney did to Obama in 2012 — as recent polls suggest.

Romney declined to comment on the state of the race in Utah and, pressed by reporters after the event, wouldn't say who will get his vote.

He focused most of his remarks at the event on what he sees as the sad state of the federal government when it comes to addressing issues.
