At stake: 36 of 2,286 primary delegates.
Caucus voters state their preference for the presidential nominee and also elect delegates to attend higher level conventions that ultimately control who Colorado's supports at the GOP's national convention. Those delegates may, but are not required, to pledge their support to the presidential candidate selected by voters. Regardless, the Associated Press is providing estimates of the number of delegates likely to have been won, but these results are not binding and could change later.
