美国宪法是美国人民设立并拥护的。所以为宪法服务，就是在为人民的目的服务。到目前为止，看起来服务得还不错。

We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America.
