Although Nevada's Democrats caucused on Saturday, the Republicans in the state have had to wait until today.
What time does this all go down?
Caucus locations in Nevada open at 5:00 p.m. local time (8:00 p.m. eastern) and must be completed by 9:00 p.m. local time. Results will start coming in shortly afterwards. (In 2012, it took days for the results to be official; but organizers are aiming to avoid a repeat of this.)
Is this caucus open or closed?
This caucus is a closed caucus, meaning that a person had until February 13, 2016 to register as a Republican in the state.
