J.B. Pritzker and his fellow Democrats ran the table on statewide offices at this week's general election. The party also picked up two seats in Congress, increased its supermajority in the state Senate, and gained a supermajority in the Illinois House. Many of the Democratic gains were rooted in former Republican strongholds outside Chicago. Do the election results suggest a permanent realignment? Or is it unique to the circumstances of 2018?
