Separated at Birth?

As Barack Obama may (or may not) be preparing to run for president, he can't avoid coming under increased scrutiny. And via Josh Marshall, CNN's Jeff Greenfield may be on to something:

The senator was in New Hampshire over the weekend, sporting what's getting to be the classic Obama look. Call it business casual, a jacket, a collared shirt, but no tie.

It is a look the senator seems to favor. And why not? It is dressy enough to suggest seriousness of purpose, but without the stuffiness of a tie, much less a suit. There is a comfort level here that reflects one of Obama's strongest political assets, a sense that he is comfortable in his own skin, that he knows who he is.

But, in the case of Obama, he may be walking around with a sartorial time bomb. Ask yourself, is there any other major public figure who dresses the way he does? Why, yes. It is Iranian President Mahmoud Ahmadinejad, who, unlike most of his predecessors, seems to have skipped through enough copies of "GQ" to find the jacket-and-no-tie look agreeable.

Maybe a turtleneck might work better . . .
