Some snips from a Heartland Institute piece on Ohio's payday lending ban:

Last November, 64 percent of the state’s voters favored approving an Ohio House bill capping payday lenders’ annualized rates at 28 percent. Legislators had passed the bill in June 2008.

The impact on the payday lending industry was swift. Already 700 of the 1,600 payday loan offices in the state have closed, said Kursman. Check ‘n Go has just 28 locations left in the state, down from 72 before the law changed, he said.

Payday lenders in Ohio argue banks have filled the void since the law changed. They don’t fall under the same regulations, so a few have started offering direct deposit advances. They typically charge $10 for an advance of $100 for up to 30 days. Banks market them as loans at 120 percent annual rates.

It wouldn't come as a surprise to learn that banks backed the payday loan ban, but I didn't find anything in an cursory Google search.
