Caucus

An unbound delegate is not required to follow the results of the other delegates in the state. The unbound delegates vote at the convention at the end of the race. More than 20 percent of GOP delegates are unbound, reports ABC News.

A caucus is where party members meet to select a candidate. Rules vary from state to state. A primary is where voters go to a polling place to cast a secret ballot.

The GOP convention will be the week of Aug. 27.
