☑ California No Party Preference (NPP) voters, make sure you request a Democratic Party Presidential ballot if you want to vote for someone running in that party (i.e. Bernie Sanders). I have read conflicting information on how to do this, so you have to contact your county office:http://www.sos.ca.gov/elections/voting-resources/county-elections-offices/
NPP voters were supposed
to get a postcard to use to request a Presidential ballot; many have not. There is also a problem in that some pollworkers have been instructed to give NPP voters a provisional ballot, which is wrong, demand a real ballot.
