Robert Mueller joined Bill Clinton in warning that anti-government groups (read: Tea Partyers) pose a genuine threat. Maybe this will prevent Republicans winking and nudging at legitimately extremist right-wing figures with guns. But probably not.

Because either the GOP is genuinely as stupid as these gun-toting idiots, or they think they need their votes. Hence Sarah Palin's new catchphrase — "don't retreat, reload." We look forward, in a grim sort of way, to hearing their excuses when the dog they've goaded with a stick attacks someone.
