ROUGH CUT (NO REPORTER NARRATION) STORY: U.S. presidential hopeful Donald Trump on Thursday (September 3) signed a pledge not to run as an independent candidate if he loses the Republican Party nomination, despite earlier refusals to rule out a third-party bid. His pledge is a victory for the party establishment in its efforts to rein in the billionaire, who leads opinion polls but has upset mainstream Republicans with his brash style and unusually personal attacks on rivals. "I see no circumstances under which I would tear up that pledge," Trump said at a campaign event. An independent Trump candidacy in the November, 2016 election could split support for the Republican Party and give the Democrats a huge boost. Nudging Trump toward signing the pledge was a weeks-long effort by Republican National Committee Chairman Reince Priebus and other officials, an RNC official said.
