Not long ago, candidate Joe Biden's most troubling behavioral tendency was the surprise outburst of belligerence. Campaigning, he'd challenge questioners to push-up contests, jam fingers in the sternums even of supporters, and plunge into rambling monologues about leg hairs and chain-fights.

Now, the president's face is often a mask of terror, like a man unsure of how he came to be standing in the middle of an intersection. Mental cars racing past, he met the press Monday, to clarify a statement made last week about Vladimir Putin: "For God's sake, this man cannot remain in power." Many interpreted this as a call for regime change. Not at all, Biden said, reading from a large-print cheat sheet — this reportedly happened — that reminded him to say he was merely expressing "moral outrage," and "not articulating a change in policy." When he ran out of pre-prepared remarks, he drifted back to danger, saying:

It's more an aspiration than anything.  He shouldn't be in power.

The AP writeup offered help: "He said he was expressing an 'aspiration' rather than a goal of American foreign policy." (I'm sure nuclear-armed Putin appreciated the semantic difference). When Biden moved more toward candor, saying he made "no apologies" for his remarks, another reporter quickly tried to guide him back to a safe harbor:

Q: Your personal feelings, sir?  Your personal feelings?

THE PRESIDENT: Personal.  My personal feelings.
