20% of American residents are not entirely happy with their health care, 80% are. I stand by that statement.

There are 308 million people living in the US. Ebbie's figure of "47 million uninsured" is 15.26% of the population.

"Unhappy" is not exactly the same as "uninsured".

I think DougR meant "15%" uninsured not "15 million people". It's more than that.
