MELISSA BLOCK, host:
A footnote now on how the Nevada caucuses will work.
ROBERT SIEGEL, host:
For the Democrats, the Nevada Delegate Selection Plan and Affirmative Action Plan is 65 pages long. In essence it says, this will be a lot like Iowa.
BLOCK: Democrats gather at 11 tomorrow morning. Once again, viability is key.
SIEGEL: Caucus goers will break into groups to indicate their preferred candidates. Groups without enough people will be declared nonviable and their members will have to go join the group of a different candidate.
BLOCK: Now, the Republicans will get together earlier at nine in the morning.
SIEGEL: They speak on behalf of their favorites candidates and then vote by secret ballot.
BLOCK: By caucusing, participants are actually selecting delegates to the county convention, who will go on to elect state delegates, who'll go on to the national convention to pick a presidential nominee.
SIEGEL: And you can read more about the issues and politics at stake in Nevada's primaries at npr.org/elections.
