I've talked about this before. We have a representative rather than a true democracy because in 1789, the latter would have been functionally impossible. But it would be easy now. The Internet is ubiquitous. Everyone has a computer or access to one.
All government actions are subject to a popular vote, with an agreed-upon quorum. Congress's function would be reduced to administrative and clerical only. And the President could not take any significant actions without the approval of the people.
Likewise, court actions would be subject to review by the people and canceled or modified if they deem it appropriate.
The rights of the people enumerated in the Constitution would remain and would in fact be strengthened, with direct referenda taking the place of long and costly court actions.
What do you think? Practical? Advisable?
