I’ll put in an early vote for Ohio, primarily because Cincinnati is located in it (though it’s right on the border with Kentucky).
Cincinnati is also known as Censornati, because it has been the point of origin of so many censorship movements, primarity Catholic in origin.
Here’s a link confirming Censornati’s “name recognition” though the full article will cost $2.50 to read. I didn’t.

Censornati was where the attempt to censor the work of Robert Mapplethorpe was made. It was where Larry Flynt was convicted of organized crime in what was clearly a set of trumped-up charges (here’s a cite)

It was also the origin of Charles Keating’s Citizens for Decent Literature, a pro-censorship group that was responsible getting Keating recognized as SUCH a wonderful, moral man (he was put in charge of an S&L and ran it so crookedly that he was the only man convicted in the savings and loan debacle of the 80s).
A speech by Nadine Strossen, president of the ACLU and author of Defending Pornography, sums it up nicely:

So I think it’s going to be REALLY hard to beat Ohio here.
That said, geography isn’t the key to censorship, it’s religion. The Catholic Church has their thumbprints all over just about every censorship movement going. Geography is a minor point in comparison. Still, if someone could see their way to nuke Censornati, I’m sure the world would be a better place all told.
