Well damn. I just checked the next least likely, the sparsely populated Wyoming. They don’t seem to have one either.
At this point, I’m giving up and going to bed.
There’s apparently no towns named after other states in Rhode Island. But there is a Carolina.
That Shit-hole counts for little! An open junkyard of discarded VW’s, crappy fudge retailers and bogus haberdasheries! Feh! I say Feh!
On a related topic: Goddamn, a lot of states have a “Douglas” County!
Virginia City, NV
Nevada City, CA
Not to mention Texico, on the Texas-New Mexico line. (Apparently Texico is all in New Mexico, with the town called Farwell on the Texas side.)
“Can you help me to find Nevada, California?” - The Jayhawks off Hollywood Town Hall
Damn good album!
There is an Ontario in California. And a Delaware County in Pennsylvania (which is not even on the river).
Calexico, California abuts Mexicali, Mexico. That has to count for something.
There’s Michigan City, Indiana. Actually probably named more for the lake than for their superior neighbors to the north.
There’s also anIowa, LA.
There’s an Onalaska, TX, which makes me wonder what there were on to name this flat, sweltering place that.
The closest Alaska comes is a town named Honolulu.
I have been to California, Maryland. I know there is a Washington, Virginia, but I don’t think I’ve been there.
There’s also an Ottawa, Ohio, just a bit west of Findlay off I-75. Nice little town.
Ottawa, OH is named after the Ottawa River, as is Ottawa, Ontario, but they are not the same Ottawa Rivers. Once would assume they got their names from the same Algonquian word.
Conversely, Toronto, Ohio was actually named after Toronto, Ontario on purpose.
Then you have the various Ontarios, the most famous of which outside Ontario, Ontario is certainly Ontario, California, inland of LA. It, too, is deliberately named after the Canadian original. The original founders were from Ontario, and so started another Ontario.
Ontario also has a Mississippi River.
I suppose Aloha, Oregon doesn’t quite count.
In Illinois we’ve got Oregon and Ohio for cities/villages (in addition to those named above), and we’ve got townships named Maine, Missouri, Pennsylvania, Tennessee, Texas, Vermont, and Virginia. Lots of townships, so lots of townships to be named. 
Alaska should count since it has Unalaska, which to me reads like every other state except Alaska 
Dakota City, Nebraska and Dakota City, Iowa
And since we’re going that way:
Toronto, South Dakota
Iowa, Louisiana (it’s pronounced differently from the state, but I don’t remember the pronunciation)
