The Daily Howler has been running an excellent series on how the so called " liberal pundits" on TV have trashed Al Gore since 1998, so that they could line their own pockets. It's sort of like " I am not a doctor but I play one on TV".

P.S. The last two links that I posted specifically mention Al, the first two basically set the stage.
