While you can expect to receive a mail ballot for this election if you’re a registered Republican voter, you won’t see some of the top GOP candidates running for president on the list.

The Nevada GOP is planning to hold a caucus two days after the Feb. 6 state-run primary, and plans to allocate delegates based on the results of the caucus and exclude any that file to run in the state primary. That’s led most major candidates, including former President Donald Trump and Florida Gov. Ron DeSantis, to file to run in the caucus, but several other Republican candidates, including former Vice President Mike Pence, still filed to run in the state’s presidential primary.

Why should I care?

This election, third on the GOP’s nominating calendar behind the Iowa caucus and New Hampshire primary, will allow Nevada Republicans to voice their preference for who they believe should be the party’s nominee for president — even if the primary does not include the full slate of candidates in the running.

Why it matters:

Though the Nevada GOP plans to use the results of the caucus to allocate Nevada’s delegates at the Republican nominating convention, a victory in the primary for a non-Trump candidate could mean a boost in media attention and momentum for that challenger.

And with mail ballots sent to every active registered Republican, the primary is likely to have higher turnout than the caucus, which is limited to a single night of voting.

Who can vote?

The presidential primary is considered a closed primary, meaning it is limited to Republican voters, and those registered as nonpartisan or with a minor party are not eligible to vote in these elections.

But same-day voter registration is in effect during the presidential primaries, which means someone who is otherwise eligible to vote can register as a Republican to vote during the early voting period or on Election Day.

Who’s in the running?

Former South Carolina Gov. Nikki Haley, former Vice President Mike Pence and Sen. Tim Scott (R-SC) are facing off against several long-shot candidates. Learn more about the candidates below.

When will voting take place?

Alongside Election Day voting on Feb. 6, early voting will run from Saturday, Jan. 27, through Friday, Feb. 2.

Mail ballots, which are sent to every active registered Republican voter, must be distributed by Jan. 17, which is 20 days prior to Election Day.

Voters eligible to use the Effective Absentee System for Elections (EASE) — which includes military, overseas and tribal voters — will have access to the online system by Dec. 23, which is 45 days before Election Day.
