"Republican presidential candidate John McCain denounced yesterday President Bush's use of "signing statements" to reserve the right to violate certain laws, and he vowed to abandon the practice if he becomes president.
"I would never issue a signing statement," the Arizona senator said at a Rotary Club meeting in Nashua, adding that he "would only sign it or veto" any legislation that reached his desk as president.
Hours later in Manchester, N.H., Democratic presidential candidate Bill Richardson agreed with McCain's stance, saying "I will eliminate them. I won't have one."
Presidents have used signing statements to declare that certain provisions of bills are unconstitutional and do not need to be enforced or obeyed, even as they sign them into law.
Bush has used signing statements to challenge more such laws than all previous presidents combined.
...
Several Democratic candidates have criticized Bush's use of signing statements, and earlier this year, Republican candidate Ron Paul promised to stop issuing signing statements if he wins. But McCain is the highest-profile GOP candidate to break with the administration over the issue."
