Freudian Slip or Showing His Hand?

A few months ago, I thought Bush was being inadvertantly truthful when he said that we could ever really win the war on terrorism. Before he corrected himself, I agreed that it will be a chronic problem for decades to come. Today, however, it looks like he slipped again (link via atrios) :

"He said that, after a debate with Kerry, 'I made it very plain. We will not have an all-volunteer army.' The crowd fell silent. 'WE WILL have an all-volunteer army,' Bush said, quickly catching himself. 'Let me restate that. We will not have a draft.'"
