In the latest installment, Miller breaks a bit of news. Surging Republican presidential candidate Newt Gingrich tells her that he is of the opinion that the District, through its restrictive gun laws, is “deliberately trying to undermine” the Supreme Court’s landmark 2008 Heller ruling.

“I deeply dislike what D.C. is doing,” he added.

Miller previously quizzed former front-runner Herman Cain on the topic. Told about her quest, Cain said, “I love it.”

Both candidates’ statements are in keeping with GOP Second Amendment orthodoxy, but it should be noted that Gingrich has a long, complicated and not particularly hostile relationship with the District and Home Rule.
