The US Constitution "applies to" the United States federal government. It is the blue print of that government, the document outlining the authority of that government, and supposedly limiting that government (although we don't do a very good job of this.) To challenge that it be shown to "apply to" you is understanding the Constitution wrongly. It wasn't written to be used for, or against the people. It was a contract among the states to empower and authorize a limited federal government with certain authorities and no more.
