In 2008 when we'll be voting for the next President of the United States, Illinois voters will have the opportunity to vote for convening a new constitutional convention. The first since 1970 which was when the current Illinois constitution was written. We may hear about revisions to this document but it's possible as is mentioned in this video that there may be a new constitution written for the state of Illinois.
I think I'm going to find more documents and articles on this because of course just as you'll hear from people promoting a constitutional convention for the sake of making changes, you will just as easily here from those who don't want this. The reason being that they don't want to allow anyone the opportunity to seriously rock the boat and maintain the status quo. Either way that decision is yours. Maintain the status quo or make some changes.
