I actually think Fox does it on purpose. They get the most unappealing Lefties to argue the Leftist line. It's smart. No matter what-- Estrich and Jackson can't sway anyone.
It must be the weekend crew getting lucky and the jackson just mugging for the cameras to capture any face time he can grasp. (ironic considering that jackson would be the type of person to curse fox, that is until it is pointed out fox has better US ratings that the other networks combined.)
