Delegates are essential during political primaries. The political primaries' goal is to choose the party's candidate for president, who must win delegates to receive the nomination.
Delegates are either won by proportion, where the candidate receives a proportionate number of delegates to the number of votes in the state's primary, or by a winner-takes-all method, where the candidate with the majority of votes in a state wins all of that state's delegates. Some states are hybrids, and some are proportional with a trigger, where the state will follow the proportional rules but allows for a winner-take-all allocation should a candidate reach a certain majority threshold.
The Democratic Party
The Democratic Party uses pledged delegate and superdelegates. There are a total of 4,750 Democratic delegates for 2020.
Pledged delegates are elected or chosen at the state level with the understanding that they will support a particular candidate, although their support is not binding. There are 3,979 current pledged delegates for 2020.
Superdelegates, also known as automatic delegates, are typically members of Congress, Governors, former Presidents, and other party leaders and elected officials. Unlike pledged delegates, superdelegates are not elected to this position and are not required to pledge their support to a specific presidential candidate, nor are they bound by the results of their state's presidential caucus or primary. There are 771 Democratic superdelegates for 2020.
Delegates will select the 2020 Democratic presidential nominee to the Democratic National Convention. To win the Democratic nomination, a presidential candidate must earn support from a majority of pledged delegates – a minimum of 1,991. President Joe Biden received 2,671 delegates in 2020 to secure his nomination for the presidential election.
The Republican Party
The Republican Party uses pledged and unpledged delegates. There are a total of 2,551 Republican delegates for 2020.
Like the Democratic Party, the Republican Party has pledged delegates that are elected or chosen at the state level with the understanding that they will support a particular candidate. There are 2,441 pledged Republican delegates.
The Republican Party also has unpledged delegates, who are each state's Republican National Committee members. Unpledged delegates must vote for the candidates that their state votes for. There are 110 unpledged Republican delegates.
Delegates will select the 2020 Republican presidential nominee to the Republican National Convention. To win the Republican nomination, a presidential candidate must earn support from a majority of delegates – a minimum of 1,276 delegates.
How Many Delegates Does Each State Have?
The number of delegates in each state depends on that state's population, similar to how the number of electoral votes depends on that state's population.
Given this, California has the highest number of delegates, with 494 for the Democratic convention and 172 for the Republican convention. California is a key state for candidates because it is the most delegate-rich state in the U.S, followed by New York, with 320 Democratic and 94 Republican, and Texas, with 228 and 155 Republican.
