SPRINGFIELD – The outgoing leader of the Illinois Senate offered a piece of advice for whoever next assumes the position – “bring everyone together.” Chicago Democrat John Cullerton surprised his colleagues in November when he announced his intention to resign from the General Assembly. He spent almost 40 years as a lawmaker, first serving in the House before moving to the Senate, where he was elected president in 2009. Senators will choose the chamber’s new president in an election Sunday, ending what Cullerton called the “very humbling experience” of campaigning for votes.
