At the Diamond Jo Casino's FanDuel Sportsbook, gamblers weren't thinking about the tax revenue they were generating.

"I don’t think about it," Art Fudge, a gambler at Diamond Jo, said. "Politics, I have nothing to do with.”

Fudge likes to place bets on football and basketball games, especially during March Madness. He said he usually takes a trip to Las Vegas during that tournament, but now he plans to stay in Iowa.

"I go to Vegas, it’s close to $900," Fudge said. "So I’ve saved that already that I can place here in Iowa."

Sportsbook General Manager Giorgio Mustica said it's been really busy.

"Customers are really liking this setting, liking this atmosphere," Mustica said. "I think it’s been great across the board.”

The Diamond Jo handled $978,825.50 in the month of September and paid out $780,691.25. It brought in $13,374.06 in state tax revenue.
