George Bernard Shaw (3,449 hits using Amazon's "Search Inside the Book" feature) George Orwell (3,271 hits) Toni Morrison (2,148 hits) Salman Rushdie (1,991 hits) Norman Mailer (1,826 hits) George Will (1,036 hits) William Safire (652 hits) Alan Dershowitz (296 hits)
Sort of fun, but it occurred to me to try a search on some other names:
Noam Chomsky: 1,921 hits Gore Vidal: 1,335 hits Howard Zinn: 387 hits Alexander Cockburn; 289 hits Victor Navasky: 162 hits Molly Ivins: 152 hits Michael Moore: Too many "Michael Moore"s in the results. Can't determine. Doug Henwood: 73 hits
And what the hell, Brian Siano: 8 hits
