His son-in-law is an OU alum and huge Sooner fan -- only good thing he said in speech along with Beat Texas and the fact that he comes from the same state as Josh Heupel -- Brokaw is not Josh! Josh is really nice, conservative, and supports the President!
His name is Allen Fry. I know him, he is a real nice guy. He's a radiologist, married to Brokaw's daughter Jennifer (also a doctor).
It's been a while, and I don't recall much about his politics, but from what I can remember, he would be appreciably to the right of Tom Brokaw.
