[P]oll numbers might be wildly different come November. But the current numbers are not without significance. They tell us, above all, that there is a great hunger that is not being satisfied. They also tell us that there is widespread unhappiness, not to say disgust, with the status quo ante. The Republican establishment seems unwilling or unable to take this on board. They are still playing the game with yesterday’s dice.
