Since money=speech in the Walkerstan Universe, it only makes sense to charge for the right to speak.
But there is that annoying business first:
U.S. Constitution: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
Wisconsin Constitution: "The right of the people peaceably to assemble, to consult for the common good, and to petition the government, or any department thereof, shall never be abridged."
I suppose with enough of their people on the Supreme Court they'll be able to find a work around.
In the meantime, King Scott is making plans and calling for his fiddlers three.
