Delegates by state
Delegates are defined as those authorized to represent others as elected representatives to a political party conference. They can be elected officials, party leaders, or grassroots activists (meaning that while delegates can include politicians, they are not necessarily so). They are allocated during the primary and caucus elections held in each state based on the results.
They then attend the party's national convention to officially nominate the presidential candidate on behalf of their state, therefore playing a crucial role in the elections.
When a candidate who has won delegates withdraws from the race, his delegates are not automatically assigned to another candidate. Delegates won by Biden, however, declared that they would support Harris following Biden's withdrawal.
