"90% of Americans support fixing gaps in government databases meant to prevent the mentally ill, drug abusers and others from buying guns. Americans also want to see better background checks for gun purchases, no matter how they’re described. More than eight in ten (86% of Americans, 81% of gun households) support background checks for all gun sales, regardless of seller or venue."
