This is about as good as it is going to get from the mainstream media. In fact, look for this to be the new Democratic approach: since the vets are credible, suggest they just remember things differently and are bitter about the anti-war stuff. Safer than attacking the vets directly, which leads to demands to release Kerry's records, and better for saying "let's all just move on, there's nothing to see here."
You just know that if Kerry was a Republican, the MSM would never again refer to his military career without adding the modifying adjective "controversial."
