All four of the “Progressive Era” amendments were ill-conceived. 18th is gone; 16, 17, and 19 need to go as well.
On the other hand, if women voters understood that one of the very few powers that the states have expressly constitutionally delegated to the feds to define domestic policy is to run the US Mail Service (1.8.7), most federal domestic spending programs based on stolen state powers and likewise stolen state revenues, such revenue stealing made easy for corrupt Congress by unconstitutional taxes in conjunction with 16th and 17th Amendments, then women might lose interest in federal issues.
“Congress is not empowered to tax for those purposes which are within the exclusive province of the States.” —Justice John Marshall, Gibbons v. Ogden, 1824.
”... the care of the property, the liberty, and the life of the citizen, under the solemn sanction of an oath imposed by your Federal Constitution, is in the States, and not in the Federal Government [emphases added].” —Rep. John Bingham, Congressional Globe, 1866. (See about middle of 3rd column.)
”From the accepted doctrine that the United States is a government of delegated powers, it follows that those not expressly granted, or reasonably to be implied from such as are conferred, are reserved to the states, or to the people. To forestall any suggestion to the contrary, the Tenth Amendment was adopted. The same proposition, otherwise stated, is that powers not granted are prohibited [emphasis added].” —United States v. Butler, 1936.
The bottom line is that the states need to eliminate the unconstitutional middleman, the unconstitutionally big federal government, from “helping” the states to manage their powers and revenues by repealing the 16th and ill-conceived 17th Amendment.
