Seriously, both she and Glen Beck are possibly the ultimate trolls, who live to provoke the masses. Witness the number of comments in this topic - this is *exactly* what she wants to see. To her it's not the contents of the replies to her remarks that matters, it's the quantity. She no doubt gets a certain sexual thrill knowing that she caused well over a thousand people to pitch in with their opinions.
In truth what she is doing doesn't really require a great deal of talent or brains, just the desire to do it. However it's particularly effective during times of uncertainty and unrest. Very simply, one needs to affirm people's insecurities about the current situation, get them good and angry about it, and then position yourself as the only one who can save them from this malaise. Allow me to officially Godwin this discussion by positing that Adolf Hitler himself was perhaps the greatest troll of all times by this standard.
