With three months remaining in office, President Bush has given us another reminder of why he will not be missed. Remember "signing statements"? That's when a president signs a bill into law, then turns around and says he has no intention of abiding by parts of that law. It's an abusive practice - and President Bush is its biggest fan. Despite criticisms such as the American Bar Association's protest that such statements undercut the constitutional separation of powers, Mr. Bush got out his pen again this week and declared that he would not be bound by sections of a military authorization act and a measure increasing the independence of inspectors general. Mr. Bush has used signing statements to object to more than 1,100 sections of laws - far more often than his predecessors. Memo to Mr. Bush's successor: If you don't like a law, do what the Constitution says. Veto it.
