For the June 5 elections, California has implemented redistricting and a top-two primary, where - except for presidential candidates - you can vote for anyone who's running, regardless of party, and the two candidates with the most votes, also regardless of party, advance to the general election. There's a great article by Torey Van Oot in the dead-tree Bee explaining all this, but it doesn't appear to be online among the race and candidate profiles - and what is there is said to be optimized for mobile, i.e. not for readers who want to see the whole thing at a glance.
I wonder if you can pick up a used Sunday Bee for a reasonable price on EBay; this one would be worth it.
