According to the most recent poll, one would think some presidential hopefuls should be dropping out soon. The poll’s margin of error is five points, so statistically Dean, Gephardt, and Kerry could be all tied. Lieberman struggles to remain with the leaders and the others are drawing insignificant support.

The laggards must realize they have no chance to win, so they are sticking around for other reasons. They may be in it for the press, or they may have other motives. Graham is probably sticking around just to increase his odds of becoming VP.
