If MN is voting GOP, then so is NH.
The states are all independent of each other. There is no uniform swing, and so the "If X goes GOP (or Dem), then Y must as well" is total BS.
And also it should be noted that each election brings new changes to the map. Trump was the First Republican to win without VA since Calvin Coolidge and without Colorado since William Howard Taft in 1908. Obama was the first Democrat to win without winning any Deep South States (Though Truman did lose many of them to Thurmond), ever. George W. Bush was the first Republican to win without Illinois if memory serves me.
Also as a note to those who made the connection between former Midwest voters swinging Florida, one needs to keep in mind that these voters could still vote Republican and Trump could lose Florida through increasing population in other areas, especially with the Puerto Rico situation.
