I don't have a problem with students campaigning wherever, but I can understand GSB's side of it. Maybe they are trying to be fair to all candidates and give equal opportunities to all of them. Maybe some candidates don't have access or resources or money to go off campus or in other areas to campaign. They should be able to wear buttons just like other state, U.S. and local elections. GSB provides experience for people who want to pursue careers in politics.
Candidates have to go out and learn how to campaign.
If they don't learn how to campaign it's going to make their career in politics more difficult. These rules are infringing on students' rights to free speech. You should be able to wear whatever whenever you want. I really don't understand how ISU can have jurisdiction over the entire town of Ames. Maybe they should hold a special session for students to vote and see who wants to change the campaign zone rules.
