The Iowa State Fair is a must-see stop on the campaign trail for presidential candidates looking for an edge in the state’s first-in-the-nation caucuses.
While this Hawkeye State tradition presents a major opportunity for White House contenders to make their case to voters hungry for personal interaction, past candidates have stumbled while navigating the grounds.
As a helpful guide to candidates who don’t want their campaigns to end at the fair, CNN Politics recruited veteran Iowa operatives to show us just how to make it through unscathed.
1. Dress casual. Fred Thompson arrived at the fair in fancy leather shoes.

2. There are lots of fried foods on sticks. Eat them! But stay away from the corn dogs.

3. When you visit the beer tent, don’t shut down the whole place like Obama did in 2012.
