Ball rarely, if ever, took a public role in politics. With control over the vast du Pont business empire, he exerted political influence through his Florida banking empire, his ownership of numerous Florida newspapers, and by funneling unregulated and unreported cash to political operatives. Ball did not need to get his hands dirty or risk personal resources. Ball was a main (but not the only) financer of the defeat of Claude Pepper's effort to be reelected to the United States Senate in 1950. Pepper's liberalism and Ball's conservatism feuded through much of the 1940s and 1950s, prompting a book to be written in 2000: "Claude Pepper and Ed Ball: Politics, Purpose, and Power".
