MICHAEL BARONE: Dems turn on Obama over Iraq, Afghanistan, Gitmo. “For it is not economics but foreign policy that has motivated the left half of the Democratic Party over the last decade. . . . Obama implicitly confessed that the view of the world held with quasi-religious fervor by the Democratic left was delusional all along. Bush didn’t lie, we didn’t go into Afghanistan and Iraq without allies and against their wishes, we didn’t carry out policies of torture, etc. The effort to cast Iraq as another Vietnam and America under Bush as an oppressive rogue power were perhaps emotionally satisfying but unconnected to reality. Without saying so, Obama has found himself having to teach this lesson to the Adam Serwers of the world. They don’t like hearing it.”
