In addition to running his fine political blog Daily Kos, Kos has been keeping track of his wife's first pregnancy on an alternate site.
Alas, his wife has just miscarried (more at fishyshark). I can only imagine the pain the couple must be feeling, but I've had occasion to imagine it pretty vividly. When my lovely bride was pregnant with our second girl, she experienced some difficulty that tinged the joyful expectation with a higher-than-usual dose of worry. Happily for us, everything turned out just wonderfully, and we have an adorable 17-month-old girl
as well as her delightful imp of a three-year-old sister.
My deep sympathies go out do Kos and his wife. I've left a message of sorrow and support on the comment thread; please do so as well if you feel inclined.
