I don't know if you've seen a map of the area, but outside of St Louis way to the south, Minneapolis is pretty much the only metro area near the states of ND, SD, NE, IA, MN. Many minorities in these states have felt marginalized for decades (particularly the Native American people, but that's a whole different story). Driving to the closest metro area in solidarity is the only choice for many people to be part of the cause they support without having to do it individually.
