I think this is not much of anything. But what I found more intriguing on the joint letter (up on the Kerry Website and provided by link on this FR thread) by the various "Wise Former Diplomatic Wonks for Kerry Group" sent to the Democrats Abroad organization prior to their weekend caucus,
and again, probably only cc'd to various news outlets like Mehri, was ONE OF THE WISE WONKS WHO SIGNED THE LETTER:
"Ambassador Joseph Wilson (aka wife of Valerie Plame) Former Ambassador to The Gabonese Republic and to the Democratic Republic of Sao Tome and Principe"
