First choice, I would change the composition of the Supreme Court to:
1. Wayne LaPierre
2. Suzanna Hupp
3. Clarence Thomas
4. Antonin Scalia
5. Neal Boortz
6. Michael Savage
7. Ann Coulter
8. Walter Williams
9. Ron Paul
Second choice, I would impose a "Three Strikes and you're Out" rule on legislators - once three laws a legislator voted for are ruled unconstitutional in whole or in part, he is automatically removed from office and banned from all government service for life.
Third choice, I would include the explicit category "None Of The Above" on all ballots. If NOTA gets the most votes, a new election is held in 3 months, but all the candidates who lost to NOTA are banned from all government jobs for a term equal to the length of the term they were campaigning for.
Fourth choice, inspired by a science fiction story: upon assuming office, all politicians would have a collar locked around their neck. Once a week, everyone who voted in the last election would have the option of "approving" or "disapproving" of their guy's performance. If the majority approve, well and good. If the majority disapprove, a shock is administered to the politician. This would go on for four weeks - four weeks of continuous disapproval would mean increasing shocks would be delivered. At the end of the fifth week, if the voters still disapprove of the poltitican, he has an option of immediate resignation or the 2 oz. of C4 in the collar detonate.
