During the 2016 Halloween Parade, a float depicting Hillary Clinton behind bars alongside campaign signs for local representative Sue Helm, who was up for reelection. People in attendance shouted "Lock her up!" as the float passed by. The incident caused some townspeople to write to the township in opposition of its approval to let the float into the parade, as the event was not meant to be partisan.[1]
