Today, I received a notification from the elections division in the California county where I live.
It read:
Do you want to vote for President on March 3, 2020? Because you are registered as No Party Preference (non-partisan), the ballot mailed to you will not contain candidates for President unless you
- re-register at www.registertovote.ca. gov with the party of your choice to receive a ballot with those presidential candidates; OR
- Return this card to request a ballot from parties allowing No Party Preference voters to vote in their primary by December 31, 2019. This one-time request will not change your party preference.
