Murkowski is toast in 2020.
Alaskans like real political leaders and not flip-flopping politicians (Which Murkowski just did).
Only Two Senators voted against the extraordinary powers afforded to President Johnson as part of the "Gulf of Tonkin" Resolution.
Wayne Morse (D-OR) and Ernest Gruening (D-AK)

Murkowski has shown her true colors, and Trumpism will likely be even less popular in Alaska in 2022 than in 2020, and she will be fully exposed as yet another sycophant for "Team Trump" and so long as DEMs run a solid contender, she will flame out.
Alaskans don't like politicians, sell-outs, and flip-floppers... they vote for political leaders with integrity, sadly and unfortunately a quality in which Murkowski appears to be lacking these days.
I’m confused about your point re: Gruening. He lost re-election to Mike Gravel in ‘68. Are you suggesting that’s because he was seen as disloyal to Johnson or something?
