They are assuming 100% of Democrats voted for Kerry and 100% of Republicans voted for Bush, which is ignorant and absurd.
I do believe the final tallies will show that a much larger percentage of Democrats voted for W then Republicans who voted for sKerry. That is something the febble minds at DU just will not accept.
There is no way that these people, DUs, do not understand how it works. They believe that if they 'think it' hard enough things will change into their favor. Kind of like Dorothy with the red shoes. Plus the fact that they think they are entitled to win.
