The Democratic and Republican front-runners are among the presidential candidates courting voters Saturday at the Iowa State Fair, but Hillary Rodham Clinton and Donald Trump are unlikely to cross paths.

The early arrival at the fairgrounds was Democrat Lincoln Chafee, who strolled the main pathway greeting voters before 9 a.m.

The former Rhode Island governor says when he takes the soapbox in the afternoon he'll extoll his executive experience and his plans for the future. He also says he hopes to check out some of the livestock. But when asked what fair food he may try, he hedged.

Chafee said, "You've got to be careful at these fairs."

Also expected at the fair Saturday are Vermont Sen. Bernie Sanders and former Pennsylvania Senator Rick Santorum.
