US Parliamentary Systems

Many of the world's democracies and republics operate not within a congressional model of government, but rather a parliamentary system. The most significant difference between a parliamentary government and the U.S. Congress is that a parliament typically encompasses the entire governmental regime, containing legislative, executive, and judicial branches within its structure, as well as the monarch, if one exists. The U.S. Congress exercises only legislative powers, and is but one of three co-equal and independent branches of the larger federal government.

In a parliament, the executive branch of the government is chosen from or by the representative branch. This generally comprises the prime minister and the governing cabinet. Congressional leaders merely administrate the daily business of Congress itself, while it is in session, and not the functioning of the national government as a whole. So, while in structure the Speaker of the House of Representatives resembles a prime minister, in substance and practice he or she only moderates the functioning of the U.S. Congress, while the wholly separate executive branch of government administrates the daily functioning of the federal government. In the U.S. Congress, legislation originates within the legislative branch, whereas in a parliamentary system, legislation is drafted by the government in power and then sent to parliament for debate and ratification.
Members of the U.S. Congress are generally elected from one of two parties, but its members are free to vote their own conscience or that of their constituents. Many members can and do cross party lines frequently. In a parliamentary system, members may be compelled to vote with their party's bloc, and those who vote against are often cast out of their respective parliamentary parties and become less influential independents. The lack of super powerful political parties allows U.S. members to more faithfully represent their constituents than members of parliament can—a member is ultimately responsible to their constituents alone, not to their party.
