It is a genuinely interesting result that is not discussed enough.
Over 55% of the state's population lives in just three counties - Douglas (Omaha), Lancaster (Lincoln) and Sarpy (Omaha suburbs). And all three swung substantially towards Biden, while most of the rural counties are completely maxed out for the GOP. It helps that those three counties are growing decently quickly, while the rural areas are generally stagnant or shrinking.
I still couldn't believe the swing in Sarpy. I know it is suburban but it isn't a huge suburban county.
