The bottom line is that the next time Senator Murkowski is up for election, there should have been a long term effort to find and fully fund a Republican candidate to challenge her in the primary.
This is a matter of “party discipline”. If necessary, another Republican should run against her as a Democrat, so that even if she manages to pull through the primary, she will still not be out of the woods.
Republican In Name Only is no longer acceptable, and RINOs need to be systematically purged from the party.
2022 is a long time away.
