So, pushing laws that are so bad that not even CA DOJ knows how to implement them is what it takes to be considered "The 'Greatest Leader' on gun control today".
On Friday Gabby Giffords and her husband, Mark Kelly, endorsed Gavin Newsom as the “greatest leader” on gun control today.
Newsom pushed Prop 63 through in 2016 to ban “high capacity” ammunition. On June 29, 2017, the ban was ruled unconstitutional and its implementation stopped by U.S. District Judge Roger Benitez.
On October 21, 2017, Breitbart News reported that Newsom asked Benitez to lift his order so the ban could take effect, but Benitez took no action. To date, Newsom’s ban remains blocked.
Nevertheless, Gabby Giffords and Mark Kelly view Newsom as gun control’s “greatest leader.” The Los Angeles Times reports that Giffords said, “Stopping gun violence takes courage, the courage to do what’s right, the courage of new ideas.” She did not explain how pushing to ban “high capacity” magazines, like Bill Clinton did in 1994, is a new idea.
