Christopher Buckley says in his wonderful introduction, "In the end, it's the New Yorker cartoonists, not the jabbering TV talking heads or pundits or spin doctors, who are the true gnostics of American politics, the keepers and tellers of its deepest truths." All that and they're funny, too! The New Yorker Book of Political Cartoons, Introduction by Christopher Buckley, Edited by Robert Mankoff, Bloomberg Press, 2000.
