As I write this Introduction the 2008 Republican National Convention is drawing to a close. John McCain's selection of little-known Alaska Governor Sarah Palin has taken the pundits by surprise, injecting new dynamics into the Presidential contest, and furnishing proof that political life is riddled with contingency. At the same time, the selection further accentuates, and perhaps even reduces to absurdity, a theme that has been at the heart of this campaign season largely due to the Democratic party primaries and their down-to-the-wire contest between Barack Obama and Hillary Clinton—the politics of difference. If the Democratic contest demonstrated that the politics of race and gender are central not simply to the Democrats but to the U.S. as a whole, the Republican convention has made it all but inevitable that for the first time in the history of the U.S. an African-American has broken the color line in Presidential politics, a woman has broken the gender line in Republican Presidential politics, and come January 2009 there will be either an African-American man or an (Alaskan American) woman in the White House as either President or Vice-President. This is extraordinary. At the same time, before this contest plays out to its conclusion—long after this introduction goes to print, and before it reaches you—there will no doubt be much tortuous discussion—and also posturing and denunciation—of the politics of race and gender and of the ways that these identities intersect with broader claims of citizenship.
