Winner Take All – All delegates are given to the winner of the contest.
Winner Take Most – Some delegates are reserved for the winner, some may be divided proportionally.
Unbound – Delegates are not bound to a specific candidate and can support any candidate of their choosing, varies by the state party organization.
