To some extent. If you vote in a rep and he lies about his policy, then the people are stuck with him for 2 or 6 years. We don't have mechanisms to impeach someone like that (some states might, but it's not a federal mechanism); his colleagues need to impeach him, which they hesitate to unless something dsmning occurs.
