THE DELEGATE SELECTION PROCESS, IN BRIEF Essentially, each party writes its own rules for the delegate selection process, and the Supreme Court has upheld their rights to do so, provided they violate no one’s civil rights. Delegates are chosen from among party activists and office-holders. In the Republican Party, each of New York’s 27 congressional districts gets to choose 3 delegates and 3 alternates. Additionally, the Republican State Committee chooses at-large delegates. In the Democratic Party, 163 pledged delegates are elected from the congressional districts, averaging 6 per district. A party member who wishes to be a delegate must get signed petitions. The Democrats also have super delegates, who are Democratic officeholders, such as the Governor, our two US Senators and 19 Democratic Congressional Representatives.
