This story from Washington State explains: “The state Democratic and Republican parties announced Tuesday they are prepared to sue to get rid of the new primary system voters just approved….The Republicans and Democrats probably joined by the Libertarians will file civil litigation seeking to throw out the “top-two primary” and the new court battle begins again said state Republican chairman Chris Vance.” I have a keen interest in this litigation, having examined the constitutionality in detail in relation to California’s Proposition 62, which voters considered (but rejected) last November.
