"I would have been a good president," he said Wednesday on Fox Business Network's "Imus in the Morning." "Maybe even a great one."

Kerry stopped short of agreeing with host Don Imus's assertion that a President Kerry would have been "better than the guy we have now."

Kerry, who ran against incumbent George W. Bush in 2004, also touched on the current debt crisis facing the U.S.

President Obama is not in trouble "yet" on the economy, Kerry said.

"We have to get the deficit on the track where people see the revenue and expenditure lines coming together instead of separating and going apart," he said.

"I think that's doable," he said. "And I think that everything has to be on the table."
