What is a characteristic that all state constitutions have in common?

A characteristic that each state's constitution has in common with others is that they all provide a framework for state government operation. This includes the judicial system and the lawmaking process.

Every state has a constitution, but some are younger than others. Additionally, some states have constitutions that are very short, while others are long and more comprehensive. Many state constitutions contain a Bill of Rights, which mostly reinforces the U.S. Constitution's Bill of Rights. The 10th Amendment of the U.S. Constitution provides each state the right to create, uphold and change its own constitution as lawmakers and the people see fit.
