Earlier this year, Madigan tried to put this before voters as a constitutional amendment, but there wasn't enough support in the House.
"Consequently I'm offering this advisory question, which, if successful, would help in the next session of the General Assembly to actually pass a constitutional amendment," says Madigan.
This is the second non-binding referendum Madigan wants on the ballot. Another would ask voters whether Illinois ought to raise the minimum wage to ten dollars an hour.
If all the pending proposals are approved, voters would face at least six questions on the November ballot.
