I don't know who needs to hear this but there hasn't been a 14 point swing in Minnesota after the state just watched it's cities get set on fire and then it's governor & mayor appease them.
Violence has been an issue in many states, and the President himself has a history of dividing the country and inciting violence. His opponent, on the other hand, has condemned violence on all sides and has a consistent message of bringing the country together.
In case you are not aware, Trump is the current President and Biden is his opponent.
That said, a poll showing a 14 point swing doesn't necessarily mean that the polling firm is garbage. Even the best polling firms with the best methodologies will produce outlier results from time to time. Their willingness to publish a poll that goes against the grain is a sign that the polling firm itself believes in their methodology. It could also be that we've seen a significant swing toward Biden in places like MN, but that swing is not 14 points and the difference is within the margin of error.
