What is a delegate in a presidential primary?
A delegate is a person authorized to represent their state at the national party convention and cast a vote toward selecting the presidential nominee. Primary voters are choosing these delegates, not the nominee directly.
When you vote in a presidential primary, you are not technically choosing the nominee directly. You are helping select delegates - real people who will travel to the national party convention and cast votes for president on your behalf. The candidate who wins a majority of delegate votes at the convention becomes the party's nominee.
Each state is allocated a fixed number of delegates by the national party. The number is based on a formula that typically weights the state's population and its history of supporting the party in general elections. Large states like California and Texas have hundreds of delegates; small states may have just a few dozen.
Most delegates are 'pledged' or 'bound' - they are legally or procedurally committed to vote for a specific candidate based on primary results for at least the first ballot at the convention. Proportional systems award delegates based on each candidate's share of the vote, while winner-take-all systems give all delegates to the top vote-getter.
If a candidate drops out, their pledged delegates may be released, depending on party rules. This becomes especially important in a contested convention where no candidate has a majority going in.
