Corruption follows the money. Highly paid jobs follow the money. By an argument purely by correlations and assumptions, I'd say that most of the people on HN have highly paid jobs in states with plenty of people, and plenty of money to spend on the tech industry, and therefore also experience some local corruption.
It's easy for a county, parish, or state to be honest when there's really nothing around to steal and no one rich enough to extort. It's only when someone shows up flashing a big wad of cash that people start to think about how to peel a few bills off of it. But then there are also plenty of places that steal as much as they can from everybody, all the time, no matter how poor, because they're the only ones around, and the system is already in place to do it.
So, in short, all rich counties are a little bit corrupt, because they're where the money is. Poor counties are either all the way corrupt, because that's the only way to pay for their corruption, or not corrupt at all, because there'd be no profit in it.
So by this hypothesis, California, Texas, New York, Florida, Illinois, Pennsylvania, Ohio, New Jersey, Georgia, North Carolina, Massachusetts, Virginia, Washington, Michigan, and Maryland are all at least a little bit corrupt. Vermont, Wyoming, Montana, South Dakota, Alaska, North Dakota, Rhode Island, Maine, Idaho, Delaware, West Virginia, New Hampshire, Hawaii, New Mexico, and Puerto Rico might possibly not be corrupt, or might be sickeningly pervasively corrupt, but you don't live there, so how would you know?
