John Edwards greets Sammie Mae Henley on her porch in Marks, Miss., the town where the Rev. Martin Luther King Jr. began his 1968 Poor People's March on Washington. Aubrey Collums, the mayor of Marks, gave Edwards the key to the city, accidentally calling him "Senator Kennedy" in the process. No one corrected the mayor's apparent reference to Robert Kennedy, who made poverty a campaign theme in 1968.
