Read the NY Times article I linked to below. It tells of some small vacation town where some of New York's richest and mightiest spend their summers. Well, apparently some of them feel they can register to vote in two locations: their legal residence be it in NY city or some expensive suburb AND their summer home's town. In fact, one of the bigshots quoted had this to say about casting a vote in both places. It sounds like something an old railroad baron would have said 100 years ago.
Here is her quote : "People are making decisions on how our taxes are spent...without the vote, we have payment without representation".
The article notes courts have refused to allow dual voting no matter how rich and no matter how many vacation homes you may own. Oh and who actually said the quote above? Well, it was Geraldine Ferraro, the first woman to run for vice president and a bigtime Democrat. I suggest you read the article and I believe the dual voters should be arrested and prosecuted.
