Transcript for Iowa Caucus Circus
things are usually pretty quiet, pretty peaceful in Iowa. But not every four years, and certainly not tonight. With the eyes of the nation now focused on the hawkeye state, it's showtime. But that doesn't mean there there's not some fun beforehand. Here's David Wright. Reporter: Here in Iowa, the circus is in town. And it's the greatest show on Earth. ? Hello Sioux City ? Reporter: Politicians channeling pop stars, taking potshots at ducks. Ted Cruz is my man. I'm voting for him. Reporter: There's even an Iowa caucus musical. ? They're always on my channel ? Reporter: A high-calorie process that starts with meat on a stick at the state fair. And often comes down to the pizza ranch strategy. And every four years, a bumper crop of candidates. Tomorrow is harvest day. David Wright, ABC news, des Moines. Harvest day indeed. Thank you for watching. I'm David Muir, I'll see you right back here tomorrow night.
