It is the GOP leadership that should be gping after Murkowski. Anyone who does not is a full-fledged RINO. Looking at her voting record, she is not an honest Republican. She has voted like a democrat in a majority of important cases. She deserves to go and should. She does not deserve to be re-elected.
China Mitch personally campaigned for years to repeal Obamacare. That failed in large part because Murkowski voted against repeal. In hindsight it is obvious McConnell never cared about Obamacare repeal. If he did he would have destroyed Murkowski politically.
