He should've renamed New Mexico to New America. I read a while back the state name causes confusion amongst those who think it's part of Mexico.

And while he's at it, Georgia could become Trumpia to avoid confusion with the nation of the same name. (Why even do you have a state named after the granddad of the king you fought off?)

But I guess those might accidentally be useful, so of course he's not going to do them. :P
