If no presidential candidate wins a majority of delegates and Republicans face a contested convention this summer, a small group of party insiders will have huge sway over who wins — and how to resolve a rift that could fracture the Republican Party.
After all the campaigning, debates and primaries, the GOP's presidential nomination could hinge on what these insiders decide.
The RNC Rules Committee decides party regulations and writes the first draft of convention rules, which are finalized by a convention rules committee and submitted to a floor vote.
Those rules are crucial. They decide which candidates are on the ballot: They could pass a rule allowing only Donald Trump to run in Cleveland, or a rule enabling new candidates to challenge him. They can decide how delegates vote — and when delegates can switch teams to support rival candidates. These are the kind of restrictions that could make the difference between a coronation or chaos in Cleveland.
