would probably just bet on the trump backed candidate in most cases, as a favorite. as a general operating principle... i don't think that's ironclad. i found your piece persuasive about the fact that there might be some evidence that it is not as iron grip as possible. what is your case for that? >> my case for that is if trump was really as strong as people think he is, he would have cleared the field in a lot of these races. he hasn't. in fact, we see a lot of governors races, a lot of senate races where the non trump endorsed candidate is staying in there and they are going to have a fight. so, he hasn't been able to clear the field. that alone says to me that he is not as strong as we think he is. secondly, you have to look at his history with endorsements. he his endorsement when wright is very high. he mostly endorsed incumbents.
