Families with ties to the military, long a reliable source of support for wartime presidents, disapprove of President Bush and his handling of the war in Iraq, with a majority concluding the invasion was not worth it, a Los Angeles Times/Bloomberg poll has found. The views of the military community, which includes active-duty service members, veterans and their family members, mirror those of the overall adult population, a sign that the strong military endorsement that the administration often pointed to has dwindled in the war’s fifth year. Nearly six out of every 10 military families disapprove of Bush’s job performance and the way he has run the war, rating him only slightly better than the general population does. And among those families with soldiers, sailors and Marines who have served in Iraq or Afghanistan, 60% say that the war in Iraq was not worth the cost, the same result as all adults surveyed.
