- Party Cohesion - UK - US

The purpose of this article is […] to examine the nature of [parliamentary] cohesion and the ways in which it is maintained. […] It is reasonable to ask after such an examination whether the cohesion of party members in the House of Commons is the product of devices which the United States could adopt, or whether it is the result of underlying factors alien to the American environment. In other words, even if desirable, would parliamentary cohesion of the British type provide a useful parallel for the United States?
