What states are the most/least in favor of free trade?

[AGA]

What states in the US are most likely to oppose free trade deals, and which states are most likely to support them? Another way to phrase this question is, if the country could have a nationwide referendum to leave NAFTA, somewhat analogous to Brexit, what would the map look like?

I assume that this map would bear little resemblance to those of recent presidential elections because recently, a lot of Republicans have turned against free trade while many Democrats now support it.

This is my more accurate map (gray states either don't care strongly one way or the other or would have their partisans flip based on what the current party leader was saying, LOL):

I think that you could make Indiana and maybe Missouri red on this map and Georgia green.
