In a chat with CBS' Bob Schieffer a few days ago, the blustery former Speaker of the House happily called for the arrest of judges whose decisions fall foul of a president and Congress. Gingrich wants Congress to issue subpoenas to bring judges in for congressional interrogations. Despite the fact that the Founders allowed for judicial review, it wouldn't be fair to expect Gingrich to follow a discipline as strict as originalism, writes Tim Cavanaugh. He's the last of the Aquarians, an impulsive sprite, enchanted with the flow of ideas and uncommitted to square, joyless principle. Gingrich's insights are ideas for a nation that is all stomach.
