The Republican blockage of any restrictions on the constitutional right to buy, own and use any sort of firearm short of a fully automatic .50 caliber machine gun is based on the presumedly unlimited sanctity of the Second Amendment. They argue it would be wrong to limit gun ownership to a few in order to preserve the right of all to have a gun for whatever reason despite the Constitution's stated purpose that citizens need to be armed to provide for an adequate militia, a purpose rendered invalid by our modern standing army, something unwanted by the Founding Fathers.
However, these same Republicans see nothing wrong in blocking the Constitutional sanctity of the right to vote for hundreds of thousands of citizens based on the slim possibility that a paltry few might misuse their franchise. Republicans even feel brave enough to undermine their specious argument by stating publicly that their obstructionist election rules will (and are intended to) limit votes by and for Democrats.
Is the right to own a gun more precious than the right to vote? Or is the Constitution nothing more than a Republican excuse to protect their own self-interest?
Republicans seem devoted to the Constitution only insofar as it enforces and protects what they want or don't want with no real regard for the document as anything more than a set of flexible "rules" to fool the electorate into believing their government is actually being run in some sort of legitimately fair manner.
