Today I've been gobbling up Randall Kennedy's book The Persistence of the Color Line: Racial Politics and the Obama Presidency. Among many great insights, this statistical point, made in a footnote and drawn from Nate Silver's blog FiveThirtyEight, struck me as particularly startling:
In 1980, nearly 98 percent of Ronald Reagan's voters were white. In 2000, 91 percent of George W. Bush's voters were white. In 2008, 89 percent of John McCain's voters were white.
