It's too bad this has been taken over by partisans.
I just talked to one of the leaders of the state Democratic Party and the arguments they offer are just full of holes and completely nonsensical. The main argument is that we should be like the rest of the other states in the country and be "normal." The top-two primary according to the Democratic Party of WA will hurt third parties and lower voter turnout. How can this be true if voters chose to have a top-two primary? It really isn't confusing, but the parties make us think that it is. And this is an exciting chance for third parties to actually become part of the system. Take advantage of it Greens, Libertarians, and Constitutionalists! You guys actually have a chance now!
They can get 15% now! Nevertheless, I like this system. Be nice if we adopted this in California. Then we could have competitive elections in the Bay Area.
