Wesley Clark didn't ask to testify at Slobodan Milosevic's war crimes trial, he was called by the prosecution. But he will be the most senior U.S. official to testify, and it did offer a nice boost for his campaign--well beyond the price of losing a few days during a crucial month.
From an AP story just posted about his first day of testimony:
"The fact that Wesley Clark is going to testify in the middle of the primaries is fairly amazing," said professor Michael Scharf, the author of several books on the tribunal.
"Clark is gambling that this will give him national and international press attention just at the time he needs it for the primaries. It will enable him to look very patriotic, very presidential," he said in a telephone interview.
But timing is everything. A week ago, it might have grabbed major press attention. The morning after Saddam's capture, a footnote.
Major bummer for him. But the story is kind of interesting, by AP standards. (It's mostly about the trial, not the campaign). You might have a look.
