This is not likely to pass, though. The proponents have no money, and the opponents have lots of money, and they've only recently started running ads against it.
Oregon is a small state, and we don't get much good polling here. Also, you musn't believe everything you read in the Washington Post. :-)
Two measures to watch are Measures 21 & 22, which would change the way we elect judges. 21 would allow voters to have a choice of "None of the above", so that there is at least some alternative to judges running unopposed. 22 would provide for the election of Court of Appeals and Supreme Court justices by district, to lessen the influence of Portland and Salem on the higher courts, which they now dominate with blatantly political liberal judges.
