THAT POLITICAL PARTIES DID NOT HOLD A RESPECTABLE PLACE IN 18th-century American political theory was a reflection of the low place they were believed to hold in practice. Wherever the Americans looked, whether to the politics of Georgian England, their own provincial capitals or the republics of the historical past, they thought they saw in parties only a distracting and divisive force representing the claims of unbridled, seKsh, special interests. I do not intend here to try to penetrate the thickets of 18th-century politics either in England or in the American provinces. We long ago learned not to identify the Whigs and Tories of the 18th century with the highly developed British political parties of modern times, and not to imagine that England had a well-developed two-party system at the close of the 18th century or even during the first two decades of the 19th. Modern parties have grown up in response to (and in turn have helped to stimulate) the development of large electorates, and their institutional structures are in good measure an outgrowth of the efforts necessary to connect the parliamentary party and the mass party. The modern party is, in this respect, the disciplined product of regular party competition in the forum of public opinion. It also deals with legislative issues, over which the established parties differ.
