You've convinced me. I think Trump should go there and have a three-hour outdoor rally in front of the biggest supermarket or shopping area in town, and then have a mega-MAGA motorcade that closes streets in advance, ties up traffic for 4-5 hours and puts police snipers on top of all the business buildings.
The best time to do this is about 5:30 pm on a Friday, so that everyone going home for the weekend after work with plans to buy groceries for a Friday night tailgate party for a h.s. football game can sit there in traffic and admire the Trump gear on all the out-of-town MAGAs disrupting their lives.
As you point out, the best way for Trump to demonstrate just exactly how much empathy he has yada-yada-yada is to come to Springfield and disrupt their lives some more,
