Illinois
All the chicago ones are rated either lock dem or pretty much dem so we'll take a look at some of the closer races
Illinois 6th Peter J Roskam (R) incumbent
vs
Sean Casten (D)
Current rating +1 point R. This area is typically 59-41 R. Roskam is currently chairman of the tax committee in the house so he's got the people who ***** about taxes vote locked up. He beat current senator Duckworth by 2 points in 2006. He's a loyal derp (was on benghazi committee, was fourth in line in the house for awhile at one point) but hasn't said any of the bat**** insane stuff outloud. (other than the standard stuff everyone else is)
His opponent is a science/engineer dude, so while 2p2 would give him points for that, it's gonna be -5 right off the bat for being a nerd in that district. And that's all I got on that guy.
Too close to call.
Illinois 12th. East St.Louis and a couple other towns and full blown deplorable world with the bonus of a green party candidate here to **** it all up. Mike Bost (R) is your incumbent, this is a R +13.3 according to 538 but also he's only up 2.7 points which he'll probably win by less votes than the green guy gets. The only thing I know about Bost is checking his twitter account where he just praised amazon for good paying jobs. Good luck running on that.
His opponent is running on bailing out pensions and other left stuff here but he's gonna be somewhere in the center. Best you can get there I'd take it.
Illinois 13th typically R+7.7 Your incumbent is Rodney Davis. Best known for beating a former miss america with a harvard JD (why are they ALWAYS republicans). Guy's a trump toad. 538 has the incumbent as +3 point fav. The University of Illinois is in this district so it's literally down to how many college kids actually bother to vote vs the rest of it, which is trumpland. He is pro weed though, which might be the difference in the end. (multiple universities are in that district actually)
Illinois 14th. The first part west of chicago area that people don't live. Another usual R 59/41 is just 3 points for R somehow. Incumbent is an evangelical investment advisor. Man do you get any more grifting than that? He's also on the science committee which I assume for republicans is entirely made up of trolls. Opponent is a black lady who served in the Obama administration. Well gl with that.
It's 11-3 lock D to R, rest I've listed above are slight favorite R and currently held by R's.
