Exceptionalism of a kind: the political historiography of US foreign relations

The recent US mid‐term elections have not only dented President Obama's image at home and abroad, they have seen the return to ‘divided government’ whereby one party controls the Executive and the other controls either the Senate or the House of Representatives or both. Such divided government has been quite frequent since the Second World War; but the situation is often portrayed by political scientists as dysfunctional, even as they acknowledge that the Founders of the Republic deliberately created a federal system which would minimize concentrations of political power. Yet divided government is only one complaint among many levelled by American commentators at their political system. This article examines such criticisms both theoretically and historically, and also develops a historical approach which discusses American attitudes to the past, particularly US foreign relations. Here the emphasis is upon the ideologies that have powered American expansion, first across the North American continent and then overseas. A peculiar, even ‘exceptional’ aspect of this expansion has been its rhetorical form, in particular the invocation of past presidents to justify contemporary actions and the creation of a doctrinal canon (classically expressed in the Monroe doctrine). While these two lines of enquiry (emphasizing history and political science) are the methodological double core of the article, they are not treated discretely; rather the focus is on the interplay between the two.
