Politico reports that 30 states are mulling calling for a Constitutional Convention. If you're wondering what articles they might consider, may I propose looking to Article II, Section 17 of the Tennessee State Constitution:

No bill shall become a law which embraces more than one subject, that subject to be expressed in the title. All acts which repeal, revive or amend former laws, shall recite in their caption, or otherwise, the title or substance of the law repealed, revived or amended.
