How Did Alvin Do It?

In Tuesday's primary, South Carolina Democrats nominated a candidate for the US Senate who did no campaigning and spent no money apart from the $10,400 filing fee.  Alvin Greene, a 32-year-old African-American military veteran who's unemployed and facing a felony obscenity charge, defeated a four-term former state legislator. He's declined a request from the state's Democratic Party to withdraw from the race against Republican US Senator Jim DeMint. Cord Jefferson of TheRoot.com, interviewed the surprise winner.
