What is the difference between sociology and political science?

Political science focuses on the formation and functions of political institutions, such as the government. Political sociology deals with the interrelation of society and politics. Political sociologists are concerned with society's effect on the institution, and vice versa. It studies the people involved in and affected by the political institutions/government, rather than focusing solely on the actual political institution, as political science does. I hope that helps! I'm actually in the process of writing about this for my political sociology class, so the subject is fresh on my mind. ~Ashley_V85~
