DETROIT — Just about every other truck that was coming or going from the Stellantis Mack Assembly plant on Jean Avenue used a honk or a thumbs-up to greet an assembled group standing on the corner of Jean and Mack holding “Autoworkers for Trump” signs.

However, not every reaction included a thumb, explained Don Shreves, who took a half-day off of work to attend the local rally. “There were occasional fingers as well,” he said, smiling. “We just wave back and tell them not to be a hater.”
