Gallup:

PRINCETON, NJ — The Supreme Court’s ruling on Thursday that a District of Columbia ban on handgun ownership is unconstitutional appears to be solidly in step with public opinion. A clear majority of the U.S. public — 73% — believes the Second Amendment to the Constitution guarantees the rights of Americans to own guns. And almost 7 out of 10 Americans are opposed to a law that would make the possession of a handgun illegal, except by the police.
