John Kartch for Americans for Tax Reform reports, WASHINGTON, D.C. – A $1,000 per gun tax should serve as a “role model” for states, according to the governor of the U.S. territory of the Northern Mariana Islands, which imposed the $1,000 gun tax earlier this month. An idea first endorsed by Hillary Clinton in 1993, steep gun taxes have now taken hold in Cook County, Ill. the city of Seattle, and now a U.S. territory.
