Those who received the card in question are registered to vote under “no party”. The card was sent to those registered under "no party" who vote by mail asking them which party’s ballot they want to vote on for the upcoming Presidential Primary Election.
The Republican Party decided they do not want anyone who is not registered as a Republican to get a Republican ballot. If you want a Republican ballot, you have to make sure you are registered as a Republican. You can change your party registration as late as Election Day.
The Shasta County Registrar of Voters, Cathy Darling Allen, said every four years there is a confusion about the Presidential Primary Elections.
"The instructions are on the back," said Darling Allen. "So, I encourage folks who have a card to turn it over and please, our phone number and website are on the back as well. So, folks can call us and ask questions...It is very confusing and we know that. The rules have changed and changed and changed. It's no surprise folks are confused or need a little help figuring out what we are asking of them. So, we are happy to have folks call us."
"The place we know there have been mistakes is at the DMV, unfortunately," said Darling Allen. "So, the DMV started registering voters in April of 2018 and I would encourage anyone who has been into a DMV to double-check their voter registration data."
