WHAT CAN PRESIDENT BUSH DO IN BAGHDAD THAT SADDAM HUSSEIN CAN'T? Appear in public. If that doesn't send a message to the Ba'athists and their would-be allies, I don't know what does.That would be pretty impressive if Bush had appeared in public. Or stayed more than a few hours. Or hadn't had to fly in under tight secrecy with all the lights out on Air Force One.
