I could not agree more. The Founders never supported universal suffrage for good reason.
It will also keep out a fair number of LIV's. "Five bucks to vote, or for a pack of smokes? ......that's an easy one."
The Framers discussed the issue at the federal convention. Since voter criteria varied so widely from state to state, they left the issue to the states.
As per Article I Section 2, voter qualifications (not withstanding subsequent amendments) are up to the states.
What the Framers DIDN’T do was create two popularly derived houses of congress.
That is the source of our misery. Repeal the 17A.
Article V.
