Republican Senator Lindsay Graham branded Donald Trump "a race baiting, xenophobic religious bigot," but that was before Trump nailed down his party's nomination. Now Graham is reportedly telling fundraisers in private to get behind Trump's campaign for the White House. Some other former critics who are now public supporters are being compared to hostages making videos to earn release from their kidnappers. But hardliners are still insisting that Trump's not just unacceptable — he's unelectable. Will he unify the GOP or destroy it?
