I doubt there's that much danger of priming here, because most people's political identification is quite well entrenched and the main effect of a question like this is going to be to call to mind that affiliation, whether or not it matches any of the options in the question.
On the other hand, I'm not quite sure why "communist" is on the list of options, especially with the explanatory text saying "for example the old Soviet Union"; there aren't a lot of advocates for Soviet-style communism around. (Last year 8 people picked this; the next most unpopular option got 35 votes, and not-answering-at-all got 30.) I doubt comparability would be badly broken by removing it.
(I'd also argue that "libertarian" is in practice a right-wing option -- e.g., libertarians tend to vote for parties of the right in preference to parties of the left[1] -- and that what's described here as "liberal" is, if you look at a broader scale than just the US, pretty much centrist. I am aware that both of these are controversial assertions, and to reduce thread-derailing I will probably not respond to comments on them. Anyway, for anyone who agrees with me the picture after removing communism would then be two right, one centre, one left.)

I doubts that true. There are a lot of people who might label themselves as conservatives or they might label themselves as libertarian.
Depending on my own mood I might self label as "Liberal" or as "Socialist" in that quiz but I'm affiliated with neither label.
I have finally gotten the survey to a point where I'm pretty happy with it. I have no big changes I want to make this year. But as is the tradition, please take a week to discuss what minor changes you want to the survey (within the limits of what Google Docs and finite time can do) and I will try to comply. In particular, we can continue the tradition that any question you request can be added to the Extra Credit section unless it's illegal or horribly offensive.
You can find last year's survey results here and you can find the very preliminary version of this year's survey (so far exactly the same as last year's) here.
EDIT: I don't particularly like the IQ test or the Big Five test used last year. If you have any better replacements for either, tell me and I'll put them in.
EDIT2: CFAR, you added seven questions last year. Let me know what you want to do with those this year. Keep them? Remove them? Replace them?
