Apparently, I wasn't the only one wondering about such a thing. Political analyst Larry Sabato just came out with a book, A More Perfect Constitution: 23 Proposals to Revitalize Our Constitution and Make America a Fairer Country, that explores just that idea. From the Amazon.com description:
The original framers fully expected the Constitution to be regularly revised by succeeding generations to reflect the country’s changing needs; yet, apart from the ten amendments in the Bill of Rights, it has only been amended 17 times in 220 years, and most of those amendments had minor ramifications. Today, partisan gridlock dominates Washington; 17 percent of voters elect a majority of senators; the presidency has assumed unprecedented and unintended powers; while politicians spend as much time campaigning for office as they do governing; and average Americans feel more and more disconnected from the political process so that half or more don’t vote in many elections—all of which would have horrified Jefferson and Madison.This one's on hold for me at the library right now, and I look forward to reading Dr. Sabato's analysis.
A More Perfect Constitution presents twenty three creative and dynamic proposals to reinvigorate American governance at a time when such change is urgently needed.
