This political season, there’s no shortage of signs. Candidates have spent thousands of dollars getting their message out. But how effective are those signs?Political expert Sandy Maisel says they’re an important part of the landscape any campaign season, but signs can get lost in cluttered words and colors. Maisel is director of the Goldfarb Center for Public Affairs and Civic Engagement at Colby College. While some messages may be easier to read than others Maisel says certain signs can be a momentum builder, especially if they’re handmade. “Because handmade signs say there’s somebody that cares enough about you to spend the time to stencil a sign. I think you want a sign that catches your eye. The green ones seem to catch your eye this time because there are fewer of them,” he says.Some of the biggest signs TV5 found were from republican front-runner Paul LePage. He has a billboard sized sign on Elm Street in Waterville. Democrat Libby Mitchell who’s on LePage’s heels in the polls also has a supersized sign in her backyard in Vassalboro.
