It really depends on which state you live in. Some state it is easy to amend their constitutions while with others the process is difficult.
To change the US Constitution you need a 2/3rds majority from Congress. I believe with state constitutions you have to have a petition with a certain number of signatures, which is hard to do, then the signatures must be checked to make sure they are authentic meaning the people who have signed the petition are from the state and they actually exist. Then it goes to the State, which they will look at the petition and I believe the State gives it to lawyers too look at and then a Judge must also look at it. If the judge disagrees, the process must start all over again.
Hopefully this helped and good luck.
