On October 15, The Oregonian, Portland’s daily newspaper, endorsed measure 90, the top-two system. The newspaper endorsed the same proposal in 2008, the year it was defeated in Oregon by a vote of 2-1.
The editorial’s main point is that U.S. House races in Oregon are now perpetually safe for incumbents. But if Measure 90 were in effect, there is no reason to think U.S. House races in Oregon would be any more exciting. Washington state has been using top-two starting in 2008, and no incumbent member of the U.S. House from Washington has been defeated, or even come close to being defeated, since top-two has been in effect.
