How does US presidency differ from a prime minister?

Answer 1

A President is an independent executive. In the United States, the President is indirectly elected by the people. He may or may not be from the majority party in the Legislature and often opposes their activities. A Prime Minister is derived directly from the Legislature making him a dependent executive. He will be both the head of the Legislature as well as the Executive creating a uniform governmental approach. However, he is seen as the representative of the party and not necessarily the representative of the people.
