We all believe it's unaffordable for families, for individuals, for businesses, for our economy and also for the federal budget.'The Congressional Budget Office today released its final cost estimates for the bill the senate passed on Christmas Eve.The CBO says the 10-year, $875 billion plan would reduce the federal deficit and cover 31 million people who'd otherwise be uninsured.Meanwhile, house leaders say they'll try to pass the measure as-is with or without the support of those anti-abortion Democrats.
