Recall petition halted things in Colorado. For how long I have no idea.
Perhaps it is time for asymmetrical politics:
Legislators that introduce or sponsor or cosponsor bills that are unconstitutional shall be immediately reported to the ethics & disciplinary committees for breach of oath of office. Ties up the system in red tape, if nothing comes of this action, this builds a case for collusion in federal court.
If the person/persons have any professional licenses (Active members of the Washington State Bar) a BAR complaint shall be filed. When their license is on the line perhaps they will think twice about committing acts of fraud against the citizenry of the state.
Go to the legislators town meetings, ask them questions. Record these sessions and place the recordings online. Questions like, "Hey if this is such a great idea to place these restrictions on firearms rights, then placing these same restrictions on (fill in the blank here) {Abortion, Voting, Health Care, Legal Counsel, Speech, Religion, etc} is reasonable too, right?"
Remind people that laws are not merely unconditional because of Articale I SECTION 24 RIGHT TO BEAR ARMS. The right of the individual citizen to bear arms in defense of himself, or the state, shall not be impaired, but nothing in this section shall be construed as authorizing individuals or corporations to organize, maintain or employ an armed body of men. But also Article II SECTION 19 BILL TO CONTAIN ONE SUBJECT. No bill shall embrace more than one subject, and that shall be expressed in the title.
EDIT:
Introduce initiatives of our own.
