Why does this Kaiser Foundation poll on people's view of Obama's health care bill contradict every other poll?

I have followed Kaiser's polling for over a year and it is just based on healthcare issues. And, if you look at the details of their polls, you will see they ask many questions about all aspects of healthcare. Ultimately, this allows them to find contradictory answers and provides them with a more accurate result than simply asking 1 or 2 questions.
