Of course the party gets what "it" wants. That's what it's for. Political parties are organizations of individual people, to which a great number of people choose to belong, despite your pompous disapproval, or they obviously wouldn't exist. They're also corporations, which conservatives constantly tell us are people. You don't have to join one, you don't have to vote for anyone who belongs to one. You can write someone's name in in your favorite color crayon. And please give me an example of a large institution that is not "corrupt." The Church, perhaps? Big Business?
