"You have to sense what you're doing to us - we're on the precipice here, about to fall into recession," said Sen. Richard Durbin, D-Ill. "Does it trouble any one of you - the costs you're imposing on families, on small businesses, on truckers?"
Its a classic example of reductionism. Reduce a complex problem to one scapegoat and score political points while lashing the goat with emotional rhetoric.
