So, the fault isn't hers, it is fault of the RINO establishment who hate to be beaten.
Rove said anything negative about 'M' from Alaska and her write-in campaign or Castle not endorsing her-I haven't seen a word about it.
Castle's endorsement wopuld have helped.
While it's entirely possible that he would have refused to endorse her in any event, the fact that Yates Walker from her campaign floated a rumor about Castle cheating on his wife with a man pretty much ruined any chance of that.
I also don't believe that independent voters in DE give a flying fig about anything Rove has to say - although they do care about what Castle says, for some reason.
