FAQs

All voters can vote in the Presidential Primary Election but voting for a presidential candidate and local county central committees depends on the political party you are registered with.

  • If you are registered to vote with a political party, you will receive a ballot that contains presidential candidates for that party only. 
  • If you are registered as a No Party Preference voter, you will receive a nonpartisan ballot, which will not include candidates for U.S. President, unless you request a different ballot. The American Independent, Democratic and Libertarian parties will allow you to crossover and vote for their presidential candidates. Request a different ballot here.
