In Nevada, the caucuses are organized and overseen by party officials, not the government. Saturday morning was the only opportunity most Republicans had to cast ballots. Democrats in Nevada held their caucuses Jan. 21.
There are roughly 74,000 Nevadans who identify as Jewish, or 2.8 percent of the state, according to 2010 Census data. It's unclear how many of those people identify as Republican or observe the Sabbath.
The caucus served somewhat as a welcome party to Jewish voters ahead of the November general election. In recent months, Republicans have stressed that Jewish voters are unhappy with President Barack Obama's stance on Israel and the Middle East, and the GOP is eager to use that dissonance to attract new voters to their ticket.
Jewish voters, long considered a safe Democratic voting bloc, are increasingly leaning Republican, according to an analysis released this week by the Pew Forum on Religion and Public Life. It found that Jewish voters favored Democrats by a 36-point margin in 2011, compared with a 52-point margin in 2008.
