Feb. 16 (Bloomberg) — There were several reports this month about the Affordable Care Act, most of them positive: Participation is up; the so-called risk corridors, which critics call a giveaway to insurance companies, will make the government money; and the law will increase labor demand.

But more attention has been lavished on the negative: Over a decade, the equivalent of 2.5 million workers will drop out of the labor force because there are alternative health-insurance options, and the employment mandate was postponed again.

Separately, the drumbeat continued around Chris Christie. The Republican governor of New Jersey held a marathon news conference more than five weeks ago as he fired top aides whom he blamed for causing huge traffic disruptions on the George Washington Bridge last autumn. Christie insisted he knew nothing about the closures, which allegedly were political retaliation against Democrats.
