The Political Chase

Don’t pull the plug yet

Kind of sounds like Hillary’s on life support.

Senator Barack Obama rolled to victory by large margins in Virginia, Maryland and the District of Columbia on Tuesday, extending his winning streak over Senator Hillary Rodham Clinton to eight Democratic nominating contests.

The outcome provided him his first chance to assert that the Democratic race, which had seemed to be heading into a protracted standoff, is beginning to break in his direction. And it left Mrs. Clinton facing weeks in which she has few opportunities for the kind of victory that would alter the race in her favor after a string of defeats notable not just for their number but also their magnitude.
