A People's History of the United States by Howard Zinn

Exerpt from Chapter 20 - The Seventies: Under Control?

Corporate influence on the White House is a permanent fact of the American system. Most of it is wise enough to stay within the law; under Nixon they took chances. An executive in the meatpacking industry said during the Watergate events that he had been approached by a Nixon campaign official and told that while a $25,000 contribution would be appreciated, "for $50,000 you get to talk to the President."

Many of these corporations gave money to both sides, so that whichever won they would have friends in the administration. Chrysler Corporation urged its executives to "support the party and candidate of their choice," and then collected the checks from them and delivered the checks to Republican or Democratic campaign committees.
