Unique boycott alert!
The Political State Report explains it - SC: NAACP exempts Prez candidates from boycott:

In an effort to end the nettlesome question of how the Confederate flag boycott will effect the South Carolina Democratic primary Post and Courier reports today that the State NAACP President James Gallman said Monday that candidates who support the boycott can spend money here on their races.

Gallman further states that the exception to the boycott existed all along:

The stance is not a change in policy, Gallman stressed, since the NAACP has allowed its members to spend money in South Carolina during the boycott as long as they are conducting "business that is vital to their success."

The NAACP further states that they never clarified their position on the boycott before because nobody asked them to.

In a related story, Dean Wormer has placed the presidential candidates on "double secret probation" citing a little known codicil in the Faber College constitution.
