What is a superdelegate in the Republican Party and how do they impact the nomination process?

A superdelegate in the Republican Party is a party leader or elected official who is not bound by the results of primaries or caucuses. They have the freedom to support any candidate they choose at the party's national convention. Superdelegates can impact the nomination process by potentially influencing other delegates and voters, as their support can carry significant weight in the decision-making process.
