<p>In Citizens United, the issue was not campaign spending. Citizen United was a non-profit corporation that had produced a film critical of Hillary Clinton and attempted to air the film in violation of the McCain-Feingold Act. Under this law, they were prohibited to have the movie shown on television within 30 days of a primary or 60 days of a general election. This sure seems like an example of govt attempting to control political debate through censorship. It may not be an egregious example, but it is worrisome that politicians are determining the guidelines for when and how the opposition is allowed to criticize them.</p>
