The campaign money might get spent on other things. But the other things don't cost as much. So campaigns would become less expensive, and the role of money would become smaller. This could make a big difference in the quality of our government. It could bring other benefits too.
People often forget that the ugliness of politics today is largely a phenomenon of television.
In person, politicians usually try to be as nice as Mr. Rogers. That's why they hire actors to do the dirty work in the ads - they want to keep their own images clean. To stop watching would be a good way to tell politicians that we are fed up with the mudslinging and character assassination, and the hired media hit-men. The whole tenor of the campaign season might improve. The best part is, there's virtually nothing to lose.
