Interesting. The US Census Bureau's 2006 figures say that there were 47 million uninsured, and there is no more recent count. Using the 2006 percentage of uninsured of 15.8% and today's Census Bureau population estimate of 305,589,973, one arrives at a figure of 48.3 million. McCain got 55.8 million votes. I assume General Powell was using some other source for one or the other of these numbers.
