State Rep. Deborah Graham (D-Oak Park), who will be sworn in Friday morning as the next 29th Ward alderman, will help choose her replacement in the Illinois House. The four-term state representative will be one of seven elected Democratic Party officials who will interview and select who will represent the state’s 78th District, which includes some of the west suburbs and parts of Chicago’s Austin neighborhood, and be the Democratic nominee for that seat in the November general election. Graham’s replacement must be named 30 days from the date she steps down from the Illinois General Assembly. Having a successor in place will be important as lawmakers could be preparing to cast votes on critical matters such as the state budget and a possible tax hike. Graham is participating in the process as the committeeman from the 29th Ward.
