Excuse my ignorance ...

The Wisconsin Constitution says that a law is not a law until it has been published.

Enactment of laws. SECTION 17. [As amended April 1977]
(1) The style of all laws of the state shall be “The people of the state of Wisconsin, represented in senate and assembly, do enact as follows:”.
(2) No law shall be enacted except by bill. No law shall be in force until published.
(3) The legislature shall provide by law for the speedy publication of all laws. [1975 J.R. 13, 1977 J.R. 7, vote April 1977

Also see Chapter 985 of the statutes.

Any such publication from any of the state agencies shall be deemed official.

Where does it say that only Doug LaFollette can publish the law?

It may also be a good time for the Tea Party Drum & Whistle Corps to begin practicing in front of LaFollette's door.
