From Congressional Quarterly:

With initial polls showing Obama scored a rhetorical victory with the public, the administration is keen to reassure wavering centrists that the changes the president is pushing in the health care system would not adversely affect middle-class voters.
Sixty-seven percent of Americans who watched the president’s speech said they favor his health care plans, a 14-point gain over the level of support before the speech, according to a CNN/Opinion Research Corp. national poll. A U.S. Census Bureau report released Thursday offered new evidence of the health coverage problem facing many Americans.
The Census found that the number of uninsured climbed again last year to 46.3 million people, an increase of 600,000 from 2007. The number covered by private insurance, either through their jobs or individual policies, dropped by 1 million. Those insured through government programs increased from 83 million to 87.4 million.
