Superdelegate

In American politics, a superdelegate is a delegate to a presidential nominating convention who is seated automatically.

In Democratic National Conventions, superdelegates—described in formal party rules as the party leaders and elected official (PLEO) category—make up slightly under 15% of all convention delegates. Before 2018, Democratic superdelegates were free to support any candidate for the presidential nomination in all rounds of balloting. (This contrasts with pledged delegates, who were selected based on the party presidential primaries and caucuses in each U.S. state, in which voters choose among candidates for the party's presidential nomination.) In 2018, the Democratic National Committee reduced the influence of superdelegates by barring them from voting on the first ballot at the Democratic National Convention, allowing them to vote only in a contested convention. In 2024, the Democratic National Committee voted to adopt new rules that allowed superdelegates to vote during the signature collection and on the first ballot of a virtual roll call for the presidential nomination, even without a candidate securing a majority of the convention's delegates using only pledged delegates, which were earned by the candidate during the primary process.^[1][2][3]

In Republican National Conventions, three Republican Party leaders of each state, territory, and Washington D.C. are automatically seated as delegates, but they are pledged to vote according to the results of their party branch's presidential primaries at least on the first ballot.^[4]
