This is a dumb idea.
The problem we have in Washington is not that we need to rewrite our Constitution; the problems are because our laws, most emphatically including our Constitution, are not being obeyed.
The federal government is radical and out-of-control. It has dramatically exceeded its authority in most cases, and is criminally negligent of many of its Constitutional duties.
Our system of "checks and balances" is broken because of excessive illicit money in politics; this includes flat-out bribery and kickbacks, as well as lobbying and other means of illicitly influencing Congress. Many Senators and Representatives vote the way a lobbying group advocates, then, upon leaving their stint of "public" service, they score cushy jobs working for these same lobbying groups; or, they support regulation favorable to an industry, then get rewarded later on by that industry. It's an obvious game they play. Nevermind drug money, the operations of foreign intelligence services, and so on....
The problem is not our Constitution; it is these people in Washington. If they would obey the letter and the spirit of the Constitution, America would be far better off. Instead, though they have taken an oath to support and defend the Constitution, they sell it - and us - out to the highest bidder, regardless of who that bidder is: foreign or domestic, legitimate or criminal.
Constitutional Convention - ConCon - is a con job if I've ever seen one. You the American people just voted for change you could believe in, and look what you got! Now, do you want the same people who sold you change in the Presidential election to sell you a change in your Constitution? Think about this one....
Besides, let's say we do change it, and somehow we change it for the better. The problem is still there: if we can't make them abide by the current Constitution, what makes you think you will make them abide by the new one?
As George Washington said:
"Should the States reject this excellent Constitution, the probability is, an opportunity will never again offer to cancel another in peace: the next will be drawn in blood."
A Constitutional Convention is a con job; rather than obeying the laws, they are manipulating you to rewrite the laws so what they do is less illegal.
A Constitutional Convention - ConCon - change you can believe in!
