You are welcome to your interpretation, of course.
It is not the Mormons who are going to be freaked out by such a barrage. It is some of the religious right or the conservatives who will freaked out if the nominee is a Mormon. They will be embarrassed to be associated with a Mormon. They will half believe what they are hearing and won’t know what to do with the information. Jumping from bashing Mormons to defending one as the nominee will be just too much of a strain.
