Michele Norris, who has spent the past week in South Carolina, reflects on what she's seen and heard from presidential hopefuls who have visited the state and from voters, many of whom remain undecided.
Since 1980, the Republican candidate who won in South Carolina has always gone on to become the party's nominee, and South Carolinians are proud of that fact. This year, however, there is no clear frontrunner among the GOP candidates, with John McCain and Mike Huckabee locked in a dead heat, so some wonder whether the tradition will continue.
On the Democratic side, the war of words between the Clinton and Obama camps on the issue of race has changed things. Obama has now pulled into the lead.
