These maps seem reasonable for the most part, but I agree with lfromnj about New Jersey and Illinois. New Jersey moved strongly towards the Democrats last year, as they nearly wiped out the state's Republican congressional delegation. It is becoming yet more diverse, and suburban voters seem to be abandoning the Republican Party in large numbers. I personally think New Jersey will still be Safe Democratic by 2050, and probably even more so than it is now. As for Illinois, not only is Chicago powerfully Democratic (and experiencing limited population loss, compared to other Midwestern cities), the Chicago suburbs (DuPage, Kane, Lake, Will, McHenry) are trending strongly towards the Democrats, canceling out Republican gains in Downstate Illinois. I think Cook County + the Chicago suburbs will keep Illinois in the Democratic column.
I would also argue that Minnesota and Pennsylvania will at least be tossup states in 2050. The Twin Cities and their suburbs are canceling out Republican gains in rural areas, while the Philadelphia and Pittsburgh suburbs, as well as places like Cumberland County, Lancaster County, etc. are moving towards the Democrats. However, I agree with Politician about most of the remaining states. Kansas will definitely be competitive by then, if Johnson County, Shawnee County, and Sedgwick County continue to trend Democratic (coupled with demographic change), and South Carolina will as well. I also think that the Upper New England states will go Republican, but I think Vermont will remain a Democratic stronghold. New Hampshire also seems to be trending
towards the Democrats, not away from them.
