ATLANTIC, Iowa -- My new piece -- and by the way, happy new year -- is a sympathetic recap of Newt Gingrich's closing bus tour here. I should be clear about the "sympathy" part. Gingrich, never a campaign finance paladin or anything, is riven with anger over the secretly funded negative ads beating him to death. His supporters are angry, too. When it hits them, even if they're philosophically okay with "money as speech," it turns out that voters think Citizens United is reuining everything.
