Take Back Your Government!: A Practical Handbook for the Private Citizen Who Wants Democracy to Work was an early work by Robert A. Heinlein. It was published in 1992 after his death in 1988.
Originally entitled How to Be a Politician, the book was written in 1946 but never found a publisher, perhaps due to excess candor. Like so many of Heinlein's works, he wrote what he knew. In this case, he based the work on his experience in California politics in the 1930s, particularly his efforts on behalf of Upton Sinclair's EPIC Movement and Sinclair's attempt to become the Democratic Party's nominee for California governor in 1934.
The book contains annotations by Jerry Pournelle, who had little time to finish, polish, or fact-check, because the publishers demanded the work be available during Ross Perot's campaign for President.
