Alaska republicans ALREADY did that... then she appealed to democrats and won as an “independent” precisely to screw the party and do things like this.
They need to run Palin for senate in Alaska and take this bitter old crone out.
Actually she ran as a Republican write-in candidate. Quite a bizarre election set up. She won without even being on the ballot - and despite comments to the contrary, the NRSC fully backed the GOP candidate and ran multiple ads on his behalf - none for Murkowski. So that told her she could win not only without conservatives, but without the Republican Party itself. She really went left after that.
