An important test for Republican presidential candidates happens Saturday — the Ames Straw Poll. It's both a fundraiser for GOP candidates and a measure of who is gaining early support in advance of the state's important caucuses next year. Three of the candidates — Jon Huntsman, Newt Gingrich and Mitt Romney — have elected not to show for this event, but they will be on the ballot. Michele Norris talks with Carol Hunter, politics editor at the Des Moines Register in Iowa, about the GOP field.
