Every topic has its own slang, it’s own lingua franca. From football’s NFL stadiums to academia’s ivory towers to California’s beaches, every niche these days maintains a coded language of its own.To really understand these niches – to be clear on what’s behind the headlines, what people are really saying, what’s really going on – you need to speak the language. And if you don’t speak the language, you better have the right dictionary.Politics, of course, is no different. Here, “deep regret” is something you express only when you feel no remorse. “Bomb throwers” are celebrated, but “bridge builders” are sellouts. And the last thing you want to be is someone’s “good friend.”To help us navigate the doublespeak and double-dealing that define the language of politics: Chuck McCutcheon and David Mark. McCutcheon is co-author of National Journal’s Almanac of American Politics and co-editor of CQ’s Politics in America 2010. Mark is Editor in Chief of Politix and former senior editor at Politico. Together, they are co-authors of the book, “Dog Whistles, Walk-Backs and Washington Handshakes: Decoding the Jargon, Slang ,and Bluster of American Political Speech."
