What good would that do? When muslims become 40% of your electorate and vote 100% for that adoption of sharia law, (57% of votes cast for), and when 50% of you traditional okies (60% of the electorate) vote against sharia law,(43% against sharia law), your state has voted for sharia law.
Are you sure sharia law has provisions for voting for retention of judges, or even for judges at all? Ask your imam.
