California is a bit weird in that the Voter Information Pamphlet doesn't have that much information. There is a sample ballot and some candidate statements but only for candidates that accept campaign finance spending limits so there are few candidate statements.

A few years ago we got rid of party primary ballots so the ballot has every candidate for every party for each office. Top two winners for each office are in the final ballot in the November election, which I guess is advantageous if one party dominates which the Democratic Party does currently (which is fine because politics shift, we used to be a Republican Party majority until I was a teenager).

For reference here's the California Republican Party endorsements. A lot of people I've never heard of.

Edit: You know I just realized I'm putting too much effort in to the Primary ballot and voting like it's a regular election. I should just vote for the best candidate in my party and then make further decisions in the November elections. So in general I'm going with CA GOP endorsed candidates unless another Republican make a much stronger case.

Governor: Jenny Rae Le Roux (R) because the CA GOP endorsed candidate Brian Dahle is all "here are the things going wrong I will fix all of it" which is not much of a plan.

Lt Governor: Angela Underwood Jacobs (R) - CA GOP endorsed candidate. Even though she didn't submit a candidate statement I'll let it pass.

Secretary of State: Rachel Hamm (R) - there is no endorsed candidate and she is the only Republican with a candidate statement.
