The reason that President Barack Obama won reelection, as most everyone knows by now, is that older white males, on whom the Republican Party has long relied, are declining in numbers, while women and minority voters, key components of Obama’s base, are increasing.  In the electoral post-mortems, Obama’s victory has been considered a kind of valedictory to white male supremacy. But his win did something else: Obama killed John Wayne on Nov. 6 -- with the complicity of roughly 61 million Americans.
