Tucker needs to stick to UFOs, space aliens and demons from other dimensions.
You mean like Art Bell?
Up to then, he was good to listen to, but right around the time he started talking about UFOs, he began overheating. It wouldn't surprise me if he were to announce he is channeling an archangel, at this point.
What causes this off-roading of the mind? Extreme popularity? Glenn Beck was a similar case. Suddenly they are talking about what they don't know, as if they alone know.
