At the moment, those occupying the anti-Donald Trump lane in the post-Trump GOP are in danger of being run over. But in the event the party’s fervor for the former president fades to any degree, or there is a rethinking of Trump’s behavior in office, Sasse may be better positioned than anyone to capitalize.

His video ricocheted around the Republican universe on Thursday night and Friday not because it was critical of Trump — as Sasse and other traditionalists have been before — but because it so directly challenged Trump’s most ardent supporters…

“He’s the first guy taking on the grassroots activists in his own party in his own state,” said Mike Madrid, a Republican strategist who worked to defeat Trump last year.

Sasse’s video, he said, was a “cold glass of water in people’s face, saying ‘the fever’s breaking.’”
