Double Edged Swords

One of the big news points right before or during Hurricane Katrina was voter ID cards:
Voting Reform Is in the Cards - New York Times

Most important, we propose building on the Help America Vote Act of 2002 to develop an accurate and up-to-date registration system by requiring states, not counties, to organize voter registration lists and share them with other states to avoid duplications when people move. The lists should be easily accessible so that voters can learn if they're registered, and where they're registered to vote.

When I saw Jimmy Carter and James Baker on TV together agreeing, I knew something was seriously wrong. Seeing this today, my first thought is "if the government starts maintaining this list of people and where they live, will it be a secret list, or will it be the ultimate spam-list?"
