Where Rauner beat Brady
In 2010 Republican challenger Bill Brady lost to Pat Quinn by less than a percentage point. This shows where Rauner made up the difference from Brady's 2010 showing. The map shows the change in total votes for the Republicans from 2010 to 2014. Red circles show where Republicans gained votes, blue where Quinn did better than 2010.
The biggest gains were all in Cook or the collar counties. While Rauner held firm downstate, he didn't pick up much more support than Brady. Quinn actually closed his margin in central Illinois, but not enough to make up for the losses around Chicago.
