The university system’s ethics office sent a notice to all employees, including faculty members, telling them that they could not wear political buttons on campus or feature bumper stickers on cars parked in campus lots unless the messages on those buttons and stickers were strictly nonpartisan. In addition, professors were told that they could not attend political rallies on campuses if those rallies express support for a candidate or political party.
That can't be legal. It certainly is stupid. Some folks at some universities--and government universities at that!--seem not to have heard of the 1st Amendment.
Government cannot tell free men and women not to express their political opinions.
