Just as Sen. John McCain once again went after Sen. Barack Obama for his willingness to engage Iran and other members of the axis of evil — before AIPAC’s annual policy conference here, no less — the Gallup organization, as I noted in my IPS story today, released the results of a new poll on precisely that question. It appears that most Americans, at least at the moment, support Obama’s position on the issue. The results can be found here.
