Since it is an election year - Part 5

Article 4 - The full faith and credit clause as well as certain rights guaranteed to the states, several of which have been superceded in the past century.

"A wise and frugal government, which shall restrain men from injuring one another, which shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned. This is the sum of good government, and this is necessary to close the circle of our felicity."  Thomas Jefferson, First Inaugural Address

Article. IV.

  Section. 1. Full Faith and Credit shall be given in each State to 
the public Acts, Records, and judicial Proceedings of every other

in which such Acts, Records and Proceedings shall be proved, and 
the Effect thereof. 
  Section. 2. The Citizens of each State shall be entitled to all 
Privileges and Immunities of Citizens in the several States. 
  A Person charged in any State with Treason, Felony, or other Crime, 
who shall flee from Justice, and be found in another State, shall on 
Demand of the executive Authority of the State from which he fled, 
be delivered up, to be removed to the State having Jurisdiction of 
the Crime.
