"We the People"

I required my students to memorize the Preamble to the US Constitution - they didn't like doing it, but I believe it will "haunt" them and they will be better citizens for it....as you gather with your friends and family to celebrate our nation's independence on the 4th of July consider these words:

We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, 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.

Which candidates are doing the most to accomplish these goals? Examples?
