I'm no fan of Beck and I know his viewership has declined sharply, but I've not found anything to support the fact that he's being phased out? .. I saw some blog posts from people making claims based on "reliable sources" and one citing a source at the new york times.. but aside from these rumor mill style posts, I've seen nothing to support that..
If Fox were smart they WOULD phase him out.. but are they really? where's your source?
