Bost: will probably get much more secure in a solidly R southern Illinois district, as he loses the St. Louis burbs in exchange for more rural area
LaHood: will be fine
Davis: probably the most vulnerable, as he gains the Metro East at the expense of some rural terrain
Shimkus: may actually be in some personal trouble; the district itself is solidly R, but he lives in the part of the seat that juts into the Metro East. He’ll probably have to move and could be vulnerable in a primary, depending on how much they mess around with his seat.
Kinzinger: I’m sure there’s a way you could mess around with the configuration of the suburbs in a way that creates real danger for Kinzinger, though I’m not sure if IL Dems will be aggressive with it (could jeopardize Underwood or even Casten if you overdo it and pull too much from their seats).
Skimkus retired, its Mary Miller now.
