President Obama's healthcare reform law coverage provisons will cost less but cover fewer people than first thought, the nonpartisan Congressional Budget Office said Tuesday. The revised estimate of the law's coverage provisions shows about 2 million fewer people gaining coverage by 2016, reducing the number of uninsured Americans by 30 million instead of the 32 million projected a year ago. That would leave about 27 million people uninsured in 2016, two years after the law's insurance exchanges go online.
