Time for the Obama Team to Rethink Their Strategy for the Remaing Primaries

The NYT says Obama is shifting his focus to McCain.  I think this is best because we see that this tit-for-tat with Clinton isn’t helping him.  He has a chance to win Indiana, and I think what’s not closing the deal for him is that he doesn’t look "presidential" to many voters.  As long as he’s caught in a bitter battle with Clinton—which he can’t win because she will take him to any low—he can’t take on the Republicans.
