That is completely not true.
John McCain’s political supporters and family don’t have a lot of say in Arizona politics as GOP insiders? He was Senator in Arizona about as long as Biden was in Delaware and Biden OWNS Delaware, politically speaking. And when he dies all this yes-men are not going to stop acting like Biden acolytes, his politics will survive him. Arizona isn’t like that though? I’m not an expert, I admit I’m an outsider, but when the opinions of McCain’s widow are reported on a national level before an election it seems to me that he still casts a long shadow in the state.
