New York City was also full of southern sympathizers, but for reasons due more to economics than politics.
There were also pockets of Union sympathisizers in the Confederate States, notably Virginia (the parts which became West Virginia), Tennessee (Knoxville area) and North Carolina (Greensboro area).
I wonder what the Kentucky national guard, sheriff's deputies, local police etc. would have to say about that, given that the state government has wiped its a** with the commiecare mandate.
