Interesting that they listed IL-17 but not IL-10.
Trump actually won the 17th, where I believe Romney lost by double digits. It's full of white union laborers (though it could end up being less so in the future if Caterpillar pulls out of Peoria) and farmers. The minority portion of that district (south side of Peoria) doesn't have that many people in it. It's not surprising that Republicans would target a district that is so demographically friendly to them with their new base. But the voters in this region are not straight-ticket voters, so just because they voted Trump (and Rauner), we can't assume that will ever trickle down ballot, even in a midterm. Still, a solid pickup opportunity.
Trump got crushed in the 10th. It's a rich lakefront suburban district, the kind of place where Trump struggled more than a anywhere else relative to Romney's showing. This would have been an extraordinarily heavy lift in a Trump midterm.
