Below, I have attached the last presidential election results for Kent County. You can interpret this how you see fit. As a whole, The west side of Michigan is known for leaning more towards the conservative side, but with that being said, there are multiple Liberal colleges directly in the city. I believe that wherever your political views are, there is a place for you in the Grand Rapids community!
