Unfortunately, this article only says that they "could" vote twice, not that they do. But I still think it has strong spin potential.
In truth, mostly it is probably stupid seniors and students (lib constitutencies) who don't bother to close out their registration in their original home state.
Notice it was 68% of democrats who do this and only 12% of repubs, but 66% of those questioned in the article were the repubs, obviously ashamed since they didn't want to talk by their actions, however notice the democrat proudly boasts of casting two votes. To me there is a difference in the attitude, not only the numbers. The repubs knew they were caught and in their shame didn't want to talk, the dem thinks it is his right to commit fraud because of his perceived opinion on how he htinks the government is run--who wants to take bet this is one of the dems who was claiming they were disenfranchised even though he had one more vote than the majority of Americans? So between the uncounted military vote and fraudulant vote of lying seniors, Bush won Florida handily, probably the popular vote too by a hair if all the dead and nearly dead voting twice vote is taken out.
