The avoidance of war talk and especially the avoidance of awkward questions about the war may be part of a larger campaign strategy to keep the president away from situations that the campaign does not tightly control. This is a president who has struggled with unscripted gaffes. He does fine when he is delivering prepared remarks with the aid of a teleprompter, but some of his most memorable and damaging comments have been when he was straying from scripted remarks or answering something other than a soft-ball question from the press. The campaign probably calculates that the risks of producing another "you didn't build that" or "the private sector is doing fine," outweigh any benefits and so restrict the access of even the largely sympathetic press corps.
