I can't even get one here in Michigan!
If you'll allow me a short story - a true story: I used to have sticker that said "Hillery doesn't trust him, why should we?" during Clinton's first election. I had that sticker on for months until one day, I went to the local library where they were hosting some NEA meeting in one of their public rooms. When I emerged quite a while later (I tend to spend a long time when I go there) the teachers' meeting had adjourned and my sticker was ripped off my bumper. I really don't think it was a NEA member, though, because they believe in the principles of free speech.
The GOP office in my city has them. If you go to the McCain website and type in your zip code, a location will come up as to where you can pick one up.
