In Presidential Primaries, voters who decline to state a political party preference (aka, No Party Preference voters) are given the opportunity to "crossover" and vote for presidential candidates without having to re-register. Some, but not all, political parties allow crossover voting. Please read our explainer on what a crossover is: https://www.nevadacountyca.gov/3745/Presidential-Primaries-and-Crossover-Vot
Our office will send postcards to all No Party Preference voters alerting them of the option to request and receive a crossover ballot. You may also request one by completing an application.
