All false political advertisements should be punishable by law. This practice falls under the "harm" or "offense" exceptions to the first amendment (freedom of thought and expression).
Why is this important?
Freedom of expression does not extend to lies to manipulate an ignorant populace. false or misleading political advertisement should be punishable by law.
Being carpet-bombed with falsehoods for political gain harms the American psyche. That practice falls under the "harm" or "offense" exceptions to the first amendment (freedom of thought and expression).
When we talk about rights (i.e. freedom of expression), we can't forget the other side of the coin: responsibility, since "freedom without responsibility degenerates into licentiousness".
