Billionaire businessman Donald Trump handily won all 50 delegates in South Carolina's first-in-the-South Republican primary in January but that doesn't mean he will keep all that support at the party's national convention.
Establishment dissatisfaction with Trump and the possibility he won't have the 1,237 delegates needed to secure the nomination on a first vote means the nominee won't be set until after the convention in Cleveland.
After the first convention vote delegates are free to support someone else.
Intense lobbying to sway delegates to another candidate if Trump doesn't win initially has been taking place in South Carolina which begins selecting national delegates this weekend.
