In many counties -- although not in Spokane -- election officials have decided to use different-colored ballots for each of the three major parties.
But who gets what color? Maybe blue is a more popular color than green, and could confer a slight advantage among indecisive voters.
So the colors were chosen by lot, under the auspices of the Secretary of State's office, which oversees elections.
Minor-party candidates -- like the Greens -- automatically advance to the November ballot.
