The longer-than-expected (and tougher-than-expected) Democratic primary contest temporarily claimed a victim in the Clinton press office this week, as spokesman Phil Singer took his first sick days since August in order to, as he told me, “clear [his] head and get over a stomach flu.”

Singer was off for a couple of days, he said, but is back at work starting today.

After I talked to Phil, one of his colleagues called to add this: "Given the last week, anytime somebody takes a couple days off, they assume the worst. But in this case the worst was a flu and not a day off since August."
