Oregon usually doesn't fall prey to the delibitating disease of let-the-incumbent-have-a-totally-free-ride, but you could understand it this year. Last time around, all five House seats were challenged, and all cruised to easy wins (and that doesn't mention the Senate race). But odds are growing that the requisite major party challeges will emerge in all five, even if the races wind up lopsided.
The latest indicator comes courtesy the new Oregon political blog Loaded Orygun, and touts the prospective candidacy of Scott Silver, a Bend-area environmental activist. It doesn't say Silver is in the race, but implies he is not far from entry. He sounds to be thoughtful activist with a range of ideas, as opposed to a narrow partisan. Which could at least make him interesting, and expose the district to some new perspectives.
If he does enter, he will not find it easy. Incumbent Republican Greg Walden was last time with 71.7% of the vote, and it was no fluke: The guy is popular, and he's been doing a capable job.
Of course, as they say in the lottery, you can't win if you don't play. And you never know.
