Barack Obama has a good question:
Obama, an Illinois Democrat, also wants a quick end to the war. On Friday, he said: ""We still don't have a good answer to the question posed by Sen. (John) Warner the last time Gen. Petraeus appeared: How has this effort in Iraq made us safer and how do we expect it will make us safer in the long run?"
Matt Stoller observes, however, that Democrats are hardly on the same page over this and many are moving with worse framing. At the end of the day, however, though the tactical ins-and-outs of the surge are interesting in an academic sense, they're only really relevant if you agree to ignore the strategic issues that Obama is raising.
