Even George Will thinks Bush has gone too far with his illegal spying.

If the Bush doctrine holds, he writes, future administrations won't even bother consulting Congress even before going to war:

Why would future presidents ask, if the present administration successfully
asserts its current doctrine? It is that whenever the nation is at war, the
other two branches of government have a radically diminished pertinence to
governance, and the president determines what that pertinence shall be. This
monarchical doctrine emerges from the administration's stance...

And derides Bush for a double standard on new interpretations of the law.
