Russ Feingold actually said...
Mr. President, the Constitution of this country was not a rough draft. We must stop treating it as such. The First Amendment is the bedrock of the Bill of Rights. It has as its underpinnings that each individual has a natural and fundamental right to disagree with their elected leaders. Not if this amendment passes. If this amendment passes, Congress can say you, the citizens, are no longer citizens, you are subjects, because we have repealed the First Amendment and taken away your ability to speak.
