What really happened to Lou Dobbs?

Considering that the source for the information in this article is MEDIA MATTERS may taint it a tad, but other sources seem to confirm the veracity of the reasoning behind Lou Dobbs sudden exit from CNN.
I often use MEDIA MATTERS as a source that is generally reliable, but I have strongly disagreed with the way they monitor and target certain personalities in an effort to get them canned (something a MEDIA MATTERS monitor did the day Imus made his ‘nappy headed ho’s’ comment). But overall they do good work that is generally commendable. To access their take on Dobbs departure, click on the link below.

Update: The smart money bet seems to be on Dobbs joining FOX NEWS (what a surprise!) on their regular or business channel, adding to their roster of extremist nut jobs, or seeking political office, a sure fire career killer that would take millions out of his pocket, assuming he is so far gone as to risk financial security to lose some election somewhere.
