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.
During the Civil War, Kentucky was a border state, but they on the south's side "team" (they had slaves and wanted to keep them). During this war, the north and south had a war, known as the Civil War. Abraham Lincoln wanted Kentucky on his side, the north side. Kentucky was a border state, therefore he wanted it to be on the north's side since it wasn't completely in the south. I believe he says he must have Kentucky because it's another state on his side to help with this war, if that makes sense.
