This article details the success thousands of hard working volunteers are having in registering the unregistered. I recently across data suggesting that in 2004 only 70% of eligible blacks in Florida were registered and only 65% of eligible blacks in Ohio were registered.
Registering those voters and getting large numbers of those voters to the polls will have obvious consequences, especially in states were outcomes in a host of races will be decided by just several thousand votes. Skeptics will say that increasing turnout will simply be a wash. Registering more Democratic voters will simply cancel out the higher number of registered Republicans.
Not so fast, my friend. Because many more of these previously unregistered belong to demographic groups (i.e. the young, the black, the beautiful) that currently trend Democratic, this has the potential to be decisive.
