Those of you saying "the next nominee will be just as bad or worse" --
It's unlikely, because there are few people worse than Chipman, who was one of the Waco killers and, more recently, a paid advocate for gun confiscation.
This nomination has been an important line in the sand, and there are a number of RKBA groups, including the Firearms Policy Coalition and the Second Amendment Foundation, that have been fighting hard against Chipman, the proud poster boy for jack-booted federal thuggery. Withdrawal of his nomination is a major victory for the cause of freedom, and thus we should look for it to be largely ignored in the mainstream news media. And yes, the administration will certainly nominate another authoritarian gun-grabber for the post, but he or she won't be as bad as Chipman...simply because there probably aren't any others that bad.
The enemies of freedom intended this nomination as a major blow against gun owners, and that blow has been successfully blocked. We should take a moment to savor that fact, even though we know more attempts are coming.
