I don't know about Campbell.
Some folks here at FR seem to be Rogan fans (pinging names from prior thread).
I personally like Rogan, but he went anti-gun when pressured.
Yes, I'm a BIG TIME Rogan fan and know him very well. Someday he'll be back. He hasn't told me yes or no about this race, but personally I'd be surprised if it were "yes". He will, someday, be a great leader for America.
