You need an Valid ID to board a train, plane or automobile.  You need to show a Valid ID to cash a check.  You need a Valid ID to accomplish many of lifes endeavors which are trivial compared to our Constitutional, Law Abiding Citizens Right to Vote.  In 33 years of active duty service, about half of it overseas, in peace and war, in every country my official duty assignment took me and mine to, Valid ID was required to do anything.  I mean anything.  What are we even discussing the Definition of "Valid ID" for?  Let us show required Valid ID, exercise one of every Citizens most incredible rights, the Right to Vote, and clean house.  Regardless of Party affiliation, our Senators and House Representatives, our Congress have failed us in action, word and deed.  The Congress's consistant example of dereliction of duty, and incedible incompetence, is why we even have debates over what should be a common-sense prerequisite to exercising your right to vote.  Get a grip.  Want to vote, show "Valid ID".  End of Discussion.
