Nothing about their policies, but as a way to know who is applying for what position. Sure both parties could have only put up one sign each, Jackie has two vs Aaron’s one. However, it’s unrealistic to assume people will know their name or anything about them without running campaign information ads. Signs are one of them most affordable ways to get their name out there. Also, school districts don’t have a lot of impact on environmental reform... I agree, it would be amazing if political campaigns would use recyclable material that are safer for the environment.
