Fifty-six percent of Americans believe opponents of the law should "stop trying to block its implementation and instead move on to other national problems," according to the poll by the nonprofit Kaiser Family Foundation. By contrast, just 38% said those opposed to the Affordable Care Act should "continue trying to block the law from being implemented." The survey of 1,239 adults—conducted over three days following the Supreme Court's historic decision last Thursday—did not pick up major changes in Americans' overall view of the sweeping legislation that Obama signed in 2010.
