I don't know if John Edwards is endorsing Barack Obama today.

Here are some hints, though.

So who's staffing Edwards today? A hint: this is Jennifer Palmieri's out-of-office message...

I will be out of the office on Wednesday, May 14. But will be checking messages intermittently. If you need assistance in the meantime, please contact [REDACTED] at [REDACTED].org for assistance.

Ms. Palmieri is a family favorite and has been called upon to staff the Edwards family at sensitive events before.

What's Wendy Button, Edwards's longtime speechwriter, been doing lately? I hear she's been writing a secret speech... (Her facebook profile includes this entry for 3pm: "Wendy just finished writing the speech.")

How come Edwards's brain trust -- all of them -- are unreachable?

Who's on this flight?
