How a candidate is chosen when no candidate wins a majority of voters in a primary election?

When no candidate wins a majority of votes in a primary election, the selection process often involves a runoff election where the top candidates face off, allowing voters to choose between them. Alternatively, some states use a proportional allocation of delegates based on the percentage of votes each candidate received, which can lead to a convention where party leaders and delegates make the final decision. Additionally, certain parties may have specific rules that govern how to resolve such situations, including negotiations or endorsements among candidates.
