At home, on issues of domestic importance, Obama is a hamstrung, hogtied president, strikingly checked and balanced. Since the passage of his embattled healthcare bill, he has, in a sense, been in chains, able to accomplish next to nothing of his domestic program. Even when trying to exercise the unilateral powers that have increasingly been invested in presidents, what he can do on his own has proven exceedingly limited, a series of tiny gestures aimed at the largest of problems. And were Mitt Romney to be elected, given congressional realities, this would be unlikely to change in the next four years.

On the other hand, the power of the president as commander-in-chief has never been greater. If Obama is the president of next to nothing on the domestic policy front (but fundraising for his second term), he has the powers previously associated with the gods when it comes to war-making abroad. There, he is the purveyor of life and death. At home, he is a hamstrung weakling, at war he is — to use a term that has largely disappeared since the 1970s — an imperial president.
