Effects of R-60
This proposed Constitutional amendment essentially creates a fourth branch of government. It alters Article I by allowing a popular vote to create law. It alters Article II by not allowing the President an opportunity to veto a law passed by an R-60 vote. It alters Article III by not allowing the Supreme Court the opportunity of judicial review of an R-60 vote. A law passed by an R-60 vote is subservient to a majority vote of both houses of Congress. Ultimate Constitutional power remains with Article I.
It is noted that an R-60 vote would take the majority of states to pass. Using data from the 2016 election, a majority of 30 states would be needed. 2016 was the most partisan election in modern history going back to 1960. All other election data shows that the R-60 referendum would take approval of more than 30 states.
