THE "OVERHAUL" CONTINUES. The president's effort to shake up the White House staff without actually changing anything took another step forward today. When Andy Card resigned, he was replaced by Office of Management and Budget Director Josh Bolten which, in turn, created an opening. That opening, we learn, will be filled by US Trade Representative Rob Portman. And just to make sure there's absolutely no new blood introduced to the system, Portman will be replaced by his deputy. This all serves as a reminder that even if the current campaign to shove Don Rumsfeld out of office were to somehow succeed, the actual results would be minimal.
