[I assume you mean current Constitution]. This is not strictly true. Some parts are obeyed and some parts not. We still have a Congress, a President and a Supreme Court, for instance. We still hold elections every 2 years. So far, 0bama has not overstayed his term limit.
It is the structural parts that are obeyed and those need to be modified - such as term limits for Congress and the Supreme Court, for instance. Congress would never vote for that but a Convention probably would.
The Court is America’s constitutional Achilles heel and would stay so even if it had to be repopulated every two Presidential terms.
The Bork Amendment, which provides for a supermajority of Congress to be able to nullify any court decision, allows for one safety valve there. The late Scalia knew of the problem and lamented it worse than any policy the court might come up with.
Actually a congress and court exist but I hardly think they are ours. As far as overstaying we have the very best situation in this cycle to actually start an uprising then all bets are off.
As far as elections are concerned..
It is enough that the people know there was an election. The people who cast the votes decide nothing. The people who count the votes decide everything. Joseph Stalin
I think this election will tell us if Joe was right.
