Polls and surveys are rarely (if ever) accurate or unbiased. That's why I riled when Bill Clinton governed by polls and poll manipulation. This survey is indicative, however, and it is disturbing.
I wouldn't call it 'cute.' It shows more than an ignorance of basics that influences a multitude of voters. Remember, this survey has the option of saying "not sure" that does not count against them (i.e. if someone answers not sure on all 8, they get a perfect score of no wrong answers). This survey shows what many people believe to be true is just wrong.
Ronald Reagan summed it up well with this quote "Well, the trouble with our liberal friends is not that they are ignorant, but that they know so much that isn’t so."
Take the concept that most people have that raising taxes by an entity will always increase the revenue for that entity. It has been shown time and time again that tax increases often decrease revenue. New York City found by raising taxes, the rich moved out and they had a substantial decline in revenue. Taxes are as much about providing power as they are about generating revenue.
