From the article:
Candidates must file their candidacy with the South Carolina GOP by Sept. 30, submitting a form that includes a signed pledge stating to hereby affirm that I generally believe in and intend to support the nominees and platform of the Republican Party in the November 8, 2016 general election.
LOL.
Well, that will mean that ALL OF HIS RIVALS will have to support NOMINEE DONALD J. TRUMP, including “Lindsey ‘I’ll punch Trump in the Nose’ Graham”...LOL.
