The first wave of county referendums in 1989 produced ten yes votes along the Mississippi River and the Missouri River. The 2002 cycle was the first time those counties had to revote, and every host county approved continued gambling. After the 2010 cycle, most counties had cleared the two-consecutive-vote threshold and locked in permanent authorization. Tribal casinos sit outside the framework because they operate under federal IGRA compacts.
The Linn County fight turned on whether the 2021 ballot language qualified for that permanent shortcut. Voters there had approved gambling in 2013 and again in 2021, but the 2021 question asked whether gambling “may continue” even though no license had ever been issued in the county. Riverside Casino petitioned the IRGC to throw the vote out on that wording. The commission heard oral argument on January 23, 2025 and declined to issue a declaratory order. The license vote followed two weeks later.
The same mechanic is the structural reason no Iowa legislator can fast-track a new commercial casino. Every future property still needs a yes vote at the county ballot before the IRGC can put it on the licensing agenda. That is also why the failed 2025 moratorium bill would have mattered. It would have suspended the IRGC’s authority to act on a county vote, not the vote itself.
