Well, in case you had any doubts about it, Springfield is a conservative city. In fact, it ranks as the 59th most conservative city in the U.S. with a population over 100,000. This according to the Bay Area Center for Voting Research. Peoria comes in at 97, Rockford and Joliet at 114 and 115 respectively, and Aurora at 125. Naperville is the most conservative Illinois city with a ranking of 45 nationally.
The most liberal city in Illinois? Chicago, coming in at number 17 nationally. Other liberal Illinois cities include Aurora at 116, Joliet at 123 and Rockford at 124. So somehow Aurora, Rockford and Joliet are both liberal and conservative...or something.
A hat tip to Kevin Drum for the pointer to this silliness.
