Davis is the only one who is possibly in trouble, but Underwood and Bustos could easily (and probably will) be more vulnerable.
Redistricting tho
Uh huh... I know.
IL-17 is already gerrymandered. Not to mention, Illinois will lose a seat, meaning if anything these seats will have to expand and not shrink down into more urban Dem-leaning areas. Not sure how Underwood is going to get some much better seat when there are 11 other Chicagoland seats and Democratic incumbents. AND it will likely be an R-leaning year, so yeah, I would still rather be Davis than Bustos.
