The Illinois House wants to let voters decide whether the state needs a lieutenant governor.
The House approved a constitutional amendment that would eliminate the office, which has long been the target of mockery.
If the Senate goes along, the measure would go on the ballot in 2014.
If approved, the attorney general would be next in line to replace a sitting governor. Supporters say eliminating the post would save $2 million a year.
Current Lieutenant Governor Sheila Simon opposes the idea, even though she is not seeking another term in the office.
