Why do Jews lean to the Left? -- a masterful analysis by Irving Kristol (1920-2009), a Trotskyite in the 1930s who would soon sour on socialism, break with the New Left in the 1960s to become the godfather of American "neo-conservatism" and commit the unthinkable -- support the Republican Party, once as "foreign to me as attending a Catholic Mass."
Commentary magazine has opened to the public their archives of his writing spanning his life. Kristol passed away last Friday.
