Correct me if I'm wrong, but it looks like the OP wasn't asking whether or not he should move to Oregon, just looking for advice concerning a move because he IS moving here. I've found that it can be pretty discouraging to have definitively made a decision, only to be told repeatedly how it's the wrong one.
Other than politics and the cost of living, we really like it here. Until quite recently the politics haven't been as bad as some think. Sure it's a generally liberal state, but historically with a strong libertarian slant. Portland is probably the most wacky hard-left city in the country. They're quite proud of their crazy weirdness. Unfortunately that population center has grown to where they run the state completely.
I absolutely hate the thought of moving away, myself. We like the fairly small town we live in, in a conservative rural county. I'm raising a young family and putting down some roots. I have a good job that I actually like. Picking up and moving, selling my house and buying another; it's a big deal and very expensive. It bugs me when people say "Just move".
It also bugs me a little when people badmouth a state as a whole. "Californian" has always been a four-letter word where I grew up, and you couldn't pay me to live there, but nowadays I'm always careful to differentiate between the nut-jobs running the state and the crazies in the big cities, and the beautiful country and good people in the more rural areas.
