The latest spate of periodic “will Joe run?” stories gave us a sense of deja vu all over again.

They pop up every time Hillary’s campaign stumbles badly, and the parlor game will continue probably until he finally says “yes” or “no.”

The last time we visited this issue, almost exactly a year ago, we wrote: “Everyone with even a passing interest in politics has likely followed the astonishing, self-inflicted, downhill slide of Hillary Clinton amid the launch of her most recent memoir, ‘Hard Choices.’ ”

We noted that Biden had recently reached out to many of his former Senate, vice-presidential and campaign staffs — when you think about it, that’s hundreds of people — and had a conference call with many of them that might have been interpreted as an organizing tool of the Biden alumni. (Planned meetings of the group eventually came to naught, we heard.)

That call was followed by a “Save the Date” invite to Biden alumni from Biden counselor Greg Schultz, who ran the Obama-Biden reelect in 2012 in Ohio for gatherings here and in Delaware last September, but apparently those didn’t work out.

Interest re-peaked this weekend, and our post colleagues Karen Tumulty, Dan Balz and Paul Kane did a fine analysis of the situation, noting that he was likely to make a decision around September.

His advisers are making sure he’s aware of the various filing deadlines and such as he makes his decision.

The obvious downside for saying “no” too early is that, the minute he does, he joins Obama as just another lame duck. (Although Obama seems to be flying pretty high these days even with one wing.)
