Early results show many voters don’t want Illinois to hold a constitutional convention.

With 18 percent of precincts reporting Tuesday, nearly 67 percent of voters marked “yes” in a referendum on the issue, while 33 percent voted “no.”

The referendum ballot asked voters whether the state should call a constitutional convention. The statewide question is required every 20 years.

Proponents say a constitutional convention would liberate Illinois from gridlocked state politics. Opponents argue a convention would result in unnecessary changes pushed by interest groups.

Last month, a judge ruled that wording on the ballot explaining the referendum was false and biased. He ordered poll workers to hand out notices about the language.
