Edit; I found it: "Blood Reign of the Dictator": (Vol. 4,2; May 1935) In the fictional state of New Cornwall, Ursus Young has become governor through bribes, cajolery, and executions by secret police. Operator No. 5 fights to stop him, but Young becomes president, dissolves the Constitution, and sets up a guillotine on the Washington Mall to destroy his enemies! His next victim will be Diane Elliot, Jimmy Christopher's lady love! Text includes footnotes about actual impeachment proceedings and their outcome.

And this could have been contemporary: "Legions of the Death-Master": (Vol. 4,4; July 1935) Death strikes down the champions of law and order as mobs wander the street spreading hatred in an insidious scheme to decimate the nation from inside.
