Question: Of the four apparent major-party candidates in the fall presidential election — Donald Trump, Mike Pence, Joe Biden, Kamala Harris — which lived in Illinois? For extra credit, what party have all four once been members? 

Answer: Kamala Harris, 55, lived in Champaign-Urbana when a youngster in the late 1960s. Her father was a professor of economics at the University of Illinois. All four have been Democrats, with Pence, a member of an all-Democrat family, becoming a Republican in 1983, and Trump, a Dem until 2001.
