Found out I had a 3rd party extension that was inadvertently hiding one of the fields in my billing/shipping address (specifically the state/region field). Something was applying a style upon page load that added "display:none;" to the field. Haven't figured out why it is being hidden yet but it definitely is supposed to be there. I don't have any extension that intentionally hides fields in my checkout and I was unable to narrow it down with Chrome's timeline tool.

I stumbled across this solution that ultimately led me to check all of my fields: Paypal Express Checkout redirects to cart for United States

PayPal of course doesn't even list that it is missing field data in the logs. Typical.
