I'm from Oregon. I like not having to pump my own gas, or at least I'm not upset about it. I grew up here and it's what I'm used to. I'd never vote or not vote for a candidate based on their stance on the issue, however. It would be different if our gas prices seemed quite a bit higher because of it, but I think it's just something that we've adjusted to. There are gas prices both higher and lower in all parts of the country than it is here, and various cities/counties have their own gas taxes anyway - there are a lot of things that go into the price. Prices throughout the state vary quite a bit. Right now here I think it's around $2.75, but I just saw it around $2.57 in a neighboring town. I'm not convinced that if we went to self-service the prices would come down much if at all - perhaps for a short time, but I just don't see it happening.
The law here was instituted a very long time ago - I think it had to do with job creation, the idea that pumping gas was unsafe, etc - they had a list of reasons when it was instituted. It's been up for a vote several times and for some reason Oregonians never overturn the law. We do a lot of things differently here than many states though - no sales tax, real minimum wage for servers, legal assisted suicide, we only vote by mail, etc.
I do like not having to get out of my car, though sometimes it means I'm at the mercy of a slow attendant. Sometimes I also have to get out anyway if they don't twist the cap enough because my car's touchy about it and the check engine light will come on sometimes. But it is nice to just hand them my card and ask them to fill it with regular, and not have to get out if it's raining/snowy/icy/super hot.
Occasionally when I go just into another state, or onto a reservation locally here, I will forget for a bit that I'm expected to get out and pump it myself. I worked in a gas station as a cashier for a bit during a college summer and was offered an extra day each week pumping gas - it was the first time I'd ever pumped gas in my life, and I declined it after the first day. I'm sure it's easy enough to get the hang of, but I was afraid (after one unfortunate incident) that I would accidentally spray gas on a car because I still had the lock on the nozzle. Plus I'm very short and it was hard for me to clean windshields.

I don't think it's beneath me to pump gas nor do I think I can't do it because I'm a woman - if it something you grow up doing I'm sure it sounds crazy not to do it yourself. It's just what we're used to around here and I don't mind it at all, and if it changed I'd get used to that in a hurry also I'm sure.
ETA - I've never once seen a sign or bumper sticker around here to the effect of "Oregonian girls don't pump gas." To each their own, but I'd kind of take offense at that as a person with some feminist leaning. Oregonian boys don't pump gas here either, so there.
