From the op-ed of Frank Rich in today's NYT.
As Tuesday’s vote looms, all that’s certain is that today’s pollsters and pundits have so far gotten almost everything wrong. Mr. McCain’s campaign had been declared dead. Mrs. Clinton has gone from invincible to near-death to near-invincible again. Mr. Obama was at first not black enough to sweep black votes and then too black to get a sizable white vote in South Carolina.
