Donald Trump works a football crowd in Iowa, hints at new 'nice' playbook

With still months to go before the Iowa caucuses, Donald Trump hopped in a golf cart here at Iowa State University and took a victory lap.

Hundreds of rowdy football fans swarmed the businessman-turned-presidential candidate Saturday as he zipped around the football stadium -- each extending a hand, hoping for a high-five, and maybe a selfie.

"Go get 'em Donald!" one man shouted as Trump worked the tailgating crowd before the day's Iowa-Iowa State game.
