The difference was big between Governor Bruce Rauner and Elect Governor JB Priztker, 15 points was the difference said University of Illinois Professor Dr. Kent Redfield. 

Incumbent Governor Bruce Rauner and Elect Governor JB Pritzker battled it out in the Illinois Governor race spending more than 230 million dollars. Only one can come out on top, and that one was JB Priztker. The difference was relatively significant, and one of the worst by an incumbent Governor said, Dr. Redfield.

It was a big rejection to Rauner in terms of how things have gone in Illinois said, Redfield. Illinois has many issues, and Rauner tried pointing out those that Democrats had done to the state. It was somewhat effective, but it didn't get all Illinoians on board.

Democrats winning DuPage County provides some concern for Republicans, with that county usually going towards Republican. In all and all Republicans lost, losing two seats in Congress up in the suburbs. 

Redfield did mention that there is some concern now with downstate and Central Illinois with the new legislators coming in.
