That noble document, the Constitution of the United States, is ofttimes praised and supposedly relied upon by the rabid, radical, right-wing, reactionary Republicans, yet, how often they do go on ad nauseam about some action they propose which is plainly and specifically outlawed by the said Constitution.
Take for instance the issuance of currency.
Article One, Section Eight, Clause Five, vests in the Congress the power to coin money.
And, Article One, Section Ten, Clause One, forbids any state from coining money or emitting bills of credit.
