From the article: 15% answered "conservative" 54% answered "liberal" 31% answered "middle of the road" Perhaps "conservative" is seen as slightly derogatory by some conservatives. Maybe the "middle of the road" conservatives got left out, because they see their views as mainstream. Also, I would imagine that liberals are more likely to lie (or exaggerate) about preferring funky ethnic foods than conservatives.
