WASHINGTON — Most Americans now say they would like to see the critics of the health care law stop trying to block its implementation and move onto other national problems, a poll released by the Kaiser Family Foundation on Monday found following last week’s Supreme Court decision upholding the overhaul.

As was the case before the historic decision, public opinion on the law to expand health care to tens of millions of Americans remains about evenly split — with 47 percent in favor of the court’s ruling and 43 percent against. Not surprisingly, the split occurs along partisan lines.

Eighty-three percent of Democrats say the law’s opponents need to move on to other issues, as do 51 percent of independents and 26 percent of Republicans — overall, 56 percent of Americans feel this way.
