And in 2012, former President Barack Obama shut down a beer tent while mingling with voters for two hours, which the owner says cost the business thousands of dollars, according to the Des Moines Register. With chants of “four more beers” heard in the background, Obama high-fived voters gathered for him in the tent.

Candidates will also participate in the Des Moines Register’s Political Soapbox, where 13 different candidates will speak for 20 minutes each to give their campaign pitch and answer questions from voters. Iowa Gov. Kim Reynolds will also host her own “fair-side chats” with GOP presidential candidates throughout the 11-day fair.
