I would like to see this law passed. Introducing a bill is not speech, it is the action that proceeds out of speech. I cannot make a statement that I dislike my neighbor by throwing firebombs at his house, even though I can credibly defend that action as "communication." Likewise, legislators should not be able to draft, introduce, or pass bills that they know are illegal without some sort of consequence. The Constitution has been toothless for much too long.
