With the official presidential campaign season now fully underway, we'll get an update on voting machines around the country. After a problem-riddled adoption of various electronic voting systems following the 2000 election, many states are now moving towards systems that can provide a voter-verified paper trail to ensure an accurate vote. In some states, voting machines that are only a few years old are being sold for scrap or auctioned on Ebay. But are there enough of the new machines to go around -- and are some areas of the country better equipped than others? And what about ballot design? We'll talk with Larry Norden, author of "The Machinery of Democracy: Protecting Elections in an Electronic World," about voting technology around the country.
