Michael Moore is registered to vote in two (2) different states.
So is Rosie.
NJ documented thousands who are registered to vote in two (2) states and did so in NJ and FL in the same year for the Presidential elections.
Same in NY, CT, MA, PA, RI.
Some in the NE vote in CT, NY, NJ in the same year.
Seems fair to me. People who are that, umm, shall we say, plentiful, should be able to vote in two states. Hell, maybe even three! ; )
