President Obama cost a small businessman about $25,000 yesterday when the Secret Service shut down his beer tent at the Iowa State Fair for security purposes prompted by Obama’s visit.

“I was in a position to make a campaign donation against my will,” beer tent owner Mike Cunningham told the Des Moines Register. The president bought 10 beers for a jovial group of fair goers, but Cunningham estimates that he lost $25,000 in sales by having his tent shut down at the most lucrative part of the day.

Cunningham told the press pool yesterday that the Secret Service shut him down at 5 pm. It’s unclear how long he remained closed, but the pool report that discusses the beer tent sequence end by saying, “At 8:34, we are heading” to another location — if that was the time that Obama left the beer tent (it’s unclear from the pool) then the beer tent would have been closed for three-and-a-half hours.

The owner, a Republican, did appreciate the “historical significance” of the president visiting his tent, the Register said, but he won’t vote for Obama.
