I started listening to him even before Coast-to-Coast when was only on KDWN. I could pick it up late at night.
I liked his show all through the 1990s.. then he wrote that book The Coming Super Storm" (or similar). Then it seemed that all his shows involved "them" (dead or aliens) telling us earthlings to "Watch it! Stop damaging the Earth." I lost interest in his show.
I recall that when he was doing week-ends after he retired he mentioned that he had put a lot of money in the idea of global warming and the industry that it would create.
From Wiki :
Bell supported Barack Obama for President of the United States in both the 2008 and 2012 elections.
