I do think Oregon is the third most vulnerable Gore state.

Oregon hates taxes. And I mean hates taxes. It's about as bad as it is in New Hampshire. They have an anti-rainy day law that forces the state government to refund any surplus annually. But their legislature meets bienially! Oregon tried to pass a tax hike to fund their schools; the consequence of not passing would be that schools would not be able to stay open for the year. The ballot referendum failed.

Also, like Washington, Georgia, Oklahoma, Colorado, and probably a few other states, Oregon suffers from the "city-state" problem, where voters from outside the city often define themselves by being of the opposite party of voters in the city, or of generally opposing or distrusting cityfolk. [in Oklahoma, interestingly, the trend is backwards; the city is Republican and the countryside is still Democratic].

Bush can win Oregon by going everywhere outside of Portland [and certain places within Portland] and saying the word "tax" as many times as he can.

Now, having said that, liberal activism is pretty hefty in Portland, so there may be enough of a ground game to put it to an end.
