Putting parts of Omaha into the same district as Lincoln is just a senseless risk on the part of the GOP. Republicans are still competitive in Omaha and last decade's Biden-won NE-02 was held by a Republican congressman, so it's not like they even have to create a Democratic vote sink. I think the parties are just a bit delusional about their ability to hang on to communities that are trending away from them.
Part of me is wanting the GOP to get its map through because of the sheer dummymander potential, the other part of me wants the state to have better districts.
