oh no! I am going to look crazy if Pritzker wins but loses some of the collar counties!
Hillary dominated in the collar counties because she wasn't Trump. Duckworth did well in them despite being Kirk's home turf because she was a very strong candidate.
Rauner is a pretty good fit for the area and considering the Dems nominated a trash-tier candidate like Pritzker, it's not surprising he's holding up (relatively) well there. The real shame is that Dems didn't take this opportunity to nominate a good (or even average) candidate and pound the IL GOP into dust. I can only imagine how Rauner would be faring against an Obama or Duckworth caliber candidate right now.
