The San Jose Mercury News has this op-ed by Marcela Miranda-Prieto, advocating that California change its top-two system to a top-five system.
Unfortunately, she says that restoring party nominees to California elections would mean that independent voters could no longer vote in California primaries. This is not true. Restoring party nominees could include a law letting independents choose a partisan primary ballot. Or California could switch to a classic open primary, in which any voter could choose any party’s primary.
