This almost looks, to me, like an intergrade...
...between a White Admiral and a Red-Spotted Purple, though, if so, it leans a lot more heavily towards the Red-Spotted Purple. I don't know if intergrades between these subspecies occur in your area, so you should get an opinion from a more-experienced contributor before you can be sure. In the meantime, you can find more information about the intergrades here.

Intergrade (clinal variant)!
Members of the "arthemis" complex form an "extensive intergrade zone" (cline) stretching across parts of the northeastern US, upper midwest, eastern regions of the Plains states northward into Canada. Traces of the white-banded/white admiral can be seen in occasional specimens as far south as Kentucky (n. Tennessee?).

I am inclined to agree, this butterfly is in fact part of the cline that connects the "southern" red-spotted purple to the "northern" white admiral.
