In 1999, Sports Illustrated named Nicklaus the “Best Individual Male Athlete” of the 20th century.
“I didn’t have that great an athletic career,” Romney quipped upon taking the stage inside the gymnasium at Westerville South High School.
“What’s a trillion? It’s a thousand billions,” Romney said. “An unimaginable amount.”
“If [Obama] were reelected, I can assure you it would be almost $20 billion,” he added.
Polls show Romney trailing the president in Ohio, a critical battleground that no Republican presidential candidate has lost while winning the general election.
A Quinnipiac University/CBS News/New York Times poll released Wednesday showed Obama up by 10 percentage points in Ohio.
"I know there are some people who want 4 more years," Romney said, "but we don't want four more years like the last four years."
