Ezra Klein on why pundits keep getting it wrong:

(P)undits only know what they’ve seen. And they’ve seen these attacks work. And so the debate finishes, and the red lights beneath the cameras blink back to life, and they go with the safe bet: Today will be like yesterday. But today is not like yesterday. And that’s why John McCain is losing.

In other words . . .

“You want it to be one way. But it’s the other way.”
