The book might almost be entitled Canadians in the Attic. Canada is the United States' forgotten twin, the country that resembles the United States more than any other, and that shares a history with America that goes back to the seventeenth century, and that includes the Revolutionary War, the War of 1812, and the anti-slavery movement, to name only a few. Canada is in a way a measure of, a barometer of, American exceptionalism. What happens in Canada is often a reflection of what has happened in the United States, but by the same token, what happens in Canada is often a sign of what could happen in its American neighbor. While the two countries have distinct political systems, and particular histories, ideologically they are closer together than standard Canadian histories suggest. (Canadians are left out of standard American histories.) Arguably, Canada is the part of North America where the New Deal came to fruition in the 1960s, when it was frustrated in the United States. But no American political idea fails to penetrate Canada, and in the 2000s many Canadians, including the current Canadian government, seek to imitate or replicate the hard-right turn in American politics. From whatever direction, the Canadian experience illuminates American experience-- and vice-versa.
