I agree with your post for the most part. I think there is something underlying Dobson's take on Thompson, either a rumor that he believes, or something he knows, or something personal. Regardless, he's said negative things twice that hit the public, so he's definitely against Thompson at this point.
I am not going to get in the way here, but I think Dr. Dobson is not going to be kindly to a man that wants no favors. Unfortunately Dr. Dobson does’nt say who he wants the Church to support.
