1. The Trump-Biden vote is an anomaly. The current NE-2 is definitely Republican. In the Congressional race, the Republican incumbent won by 4, and the only time a D won the seat in the last 20 years is when a tea-party 3rd part candidate split the R vote in 2014. I think the district is currently listed as R+4, and I'm betting this will likely take it to R+6. It turns an R lean into a likely, or maybe even a safe.
2. I hate this notion that a fair compromise is to hold serve, or slightly lose. The population trends should take bias the district blue over time. Instead, every ten years a Republican Unicameral gerrymanders the district to preserve the status quo from the previous gerrymandering. The census shows the urban population in the district was underrepresented in 2020. The R+4 should have been more like an R+2 (just as a hypothetical). Instead of drawing the lines to pull back from the the rural areas, this map cuts out a central corridor of the metro area, and adds in a Saunders County, which is due north of Lincoln. It is absolute fuckery, and is justified as preserving the previous decades fuckery.
I get it that you are not claiming this to be a fair compromise, just an acceptable one.
FWIW, it hasn't completely passed yet, just the first round of votes.
