Oh come on:

Legal experts say that President Bush had the unquestionable authority to approve the disclosure of secret CIA information to reporters, but they add that the leak was highly unusual and amounted to using sensitive intelligence data for political gain.

"It is a question of whether the classified National Intelligence Estimate was used for domestic political purposes," said Jeffrey H. Smith, a Washington lawyer who formerly served as general counsel for the CIA.

It’s a question of ethics. Just because something is technically legal doesn’t mean it’s ethical. The GOP, who pilloried Clinton for his extramarital blowjob long before he broke the law by lying under oath, certainly understand the distinction between something that is legal, but not ethical. But obviously, as always, their ethical code is a highly subjective one. By my calculations, if a president does something unethical that only affects his inner circle, that’s an unbelievable outrage. However, if a president does something unethical that affects national security and endangers the life of covert CIA operatives, that’s just peachy. Interesting.
