The Congressional Record began publication in 1873.

The passage of Citizens United by the Supreme Court in 2010 sparked a renewed debate about campaign spending by large political action committees, or Super PACs. Its ruling said that it is okay for corporations and labor unions to spend as much as they want in advertising and other methods to convince people to vote for or against a candidate. This book provides a wide range of opinions on the issue. Includes primary and secondary sources from a variety of perspectives; eyewitnesses, scientific journals, government officials, and many others.
