One reason is that Nevada Democrats will have only 32 votes of the 2,162 needed to nominate a presidential candidate at the party's national convention in July.
Another reason is that the caucuses are conducting what amounts to a nonbinding straw poll in which no delegates will be committed to particular candidates. Most of Nevada's delegates won't be committed to a candidate until the state Democratic convention in April.
