These are the first general election presidential polls for Minnesota and Oklahoma that I am aware of. Neither is a surprise. Minnesota is solidly supporting Hillary Clinton, and Oklahoma is solidly supporting Donald Trump.
The Star-Tribune Poll was done between September 12th and 14th of a random sample of 625 Minnesota voters, and has a margin of error of 4 points.
The Sooner Poll was done between September 13th and 15th of a random sample of 515 Oklahoma voters, and has a margin of error of 4.32 points.
