While much of what will happen on Election Day is now unknowable, we can predict with certainty that President Obama won't win a majority of the white vote.
No news there. No Democratic presidential candidate, after all, has received the support of most white voters since President Lyndon Johnson's 1964 historic rout of Sen. Barry Goldwater of Arizona.
Still, four years ago, Obama did manage to get a very respectable 43 percent of white voters to choose him over Goldwater's Senate successor from Arizona, Sen. John McCain.
That was then.
