Trump lost a bit of suburban support in a lot places. It seems the GOP Never Trump validation of the “Trump character” nonsense took its toll a bit. Sasse in Nebraska is a good example.
Nevertrumper vote is evident in Michigan too, where the GOP Senate challenger is running about a percentage point ahead of Trump, and currently winning.
If Trump’s holds PA, GA and NC, then Biden wins with 270, making that Nebraska vote absolutely decisive in preventing a tie (which is the same as a Trump win). At least Trump did visit that state. But it would sting to not have poured more resources into securing all of Nebraska if this is a 1 EV loss.
