A-list director and writer David Mamet is an Oscar and a Tony Award-nominee and a Pulitzer-Prize winner. A true rarity, this successful Hollywood screenwriter has "come out" (as Fox put it) as a political conservative. This, of course, can be tough in a world that is dominated by left-leaning minds.
