Yesterday, May 31, Barack Obama criticized John McCain for his statement that the Iraq surge was working and that troop levels had diminished since it was instituted.

McCain, as typical, was dead wrong and Obama is to be commended for his criticism.  After leveling it, however, he moved into other terrain that proved considerably less firm.  

Obama criticized McCain for his failure to admit making a mistake, indicating that all political figures of any duration ultimately make them.  He noted that the problem was in failing to admit making mistakes and move on.

The next point Obama made was to draw an analogy between McCain and George W. Bush in Iraq.  He noted that Bush's serious problem was his failure to concede that he had made a mistake in Iraq.
