Well since Obama's win and the "polls" (which once again have proved to be useless) predicted that Hillary wouldn't do so well in New Hampshire it was time for deserpate measure. So at a campaign stop Hillary was asked a question and the "tears" started to appear. No doubt the media ate this up, and give her all the attention she needed with the added victim mentality that is common among democrats.
This obviously worked out for Hillary as she took the New Hampshire primary. However, the real tragedy here is how stupid a great part of the population is that they can't see through Clinton and her fake display of emotion.
