With McConnell gone, Murkowski won’t run for re-election. She needed McConnell’s money to beat back the conservative in the top 4 rank-choice run-off. I don’t think we ever got a vote from Murkowski when her vote mattered.
Sue Collins is another matter. She represents a blue state. She has to be careful with votes. But, she has come through for our side on selected votes.
I hope you are right!
