Tom Perez, chairman of the Democratic National Committee, told The Associated Press that several factors, including early voting and potentially high turnout, could affect the tabulation and timing of results. In addition, Nevada, like Iowa, will be reporting three sets of data from the multistage caucus process.

Perez said he doesn’t know when results will be released. “We’re going to do our best to release results as soon as possible, but our North Star, again, is accuracy,” he said late Tuesday after touring an early voting site in Las Vegas.

Nevada Democrats are hoping to avoid a repeat of the chaos that ensnared the Iowa caucuses this month. Unlike the November general election and state primaries that are run by state and local election officials, the caucuses are administered by state parties.
