Gun-control advocates are mapping state firearms bills if Democrats seize full control of several legislatures in November, though the White House would still block federal statutes. Pennsylvania needs three Senate seats and a larger House majority for major limits, a Bloomberg-funded site said, after Virginia passed over a dozen bills; Colorado-style permits and taxes on federally listed items could follow though an assault-weapon ban looks unlikely given next year’s Court ruling. Minnesota, Wisconsin and Arizona could also see Democratic trifectas elevating gun limits despite little campaign focus, but none is locked and gun owners voting may decide.
