The charts above are from a Gallup Poll -- done between February 15th and 21st of a national sample of 3,753 adults, with a 2.2 point margin of error.
It shows that about 18% of the public says they would not be able to afford healthcare if they needed it today. That's shameful in a developed country like the United States -- and other developed countries provide healthcare or insurance that would enable their citizens to get healthcare. It's only in the United States that nearly one in five people cannot afford healthcare.
The second chart shows the public wants Congress to address this problem. And about 60% would support making Medicare available to everyone.
