Dermot, Murkowski was never on the list of Trump campaign supporters.  While other Alaska and national Republicans put their names on the Trump campaign just because he was voted the Republican nominee, Murkowski withheld her support from day one.  

In August she said, "I’m not a fan of Donald Trump. He’s made statements and raised opinions that I certainly can’t defend. In fact, some of them I find offensive. I am looking along with a lot of Americans to see, OK, going forward in these next few months – what is he going to be laying down? What is he going to be putting down in terms of policies. How is he going to assure me as a woman, how is he going to assure me as an Alaskan who represents a state like ours, how is he going to assure me that he is going to make our nation safer?”

Murkowski gave Trump a chance to show he was worthy of her support as a woman, an Alaskan, and an American. Murkowski's concerns were justified.  She's said so.  You should be praising her.
