An Open Question

I sent this recently to the White House (yeah, I know, I'm probably already wiretapped):

If (as shown in various reports by the media) the President may, by virtue of his 'inherent authority as Commander-inChief,' authorize domestic spying without warrant or court oversight, and if he may circumvent the expressed will of the people of the United States (as given by the Congress in the bills it sends up) through bill-signing statements, why doesn't President Bush simply abrogate the Constitution, declare a dictatorship and dissolve the Congress?
