Number of those without health insurance about 46 million

It's a statistic often quoted by Democrats during the health care debate: 46 million people without health insurance.

"Now, health insurance reform is one of those pillars that we need to build up that new foundation," said President Barack Obama at a town hall in New Hampshire. "I don't have to explain to you that nearly 46 million Americans don't have health insurance coverage today. In the wealthiest nation on Earth, 46 million of our fellow citizens have no coverage. They are just vulnerable. If something happens, they go bankrupt, or they don't get the care they need."
