Making Sense of Ballot Propositions

With the election season upon us once again, now is a good time for a primer on how the ballot measures numbering system works.

• Propositions in the "100" series are constitutional amendments initiated by the people, or referred to the ballot by the Arizona Legislature.
  
• Propositions in the "200" series are citizen initiatives to create new state laws, or to amend current statutes.
  
• Propositions in the "300" series are referred to the ballot by the Arizona Legislature to create new state laws, or to amend current statues.
  
• Propositions in the "400" series deal with local matters.
  

I hope that helps.
