Our constitution is flawed. A convention to fix it would be foolhardy.

The U.S. Constitution is flawed and ought to be changed.

Here's where I'd start:

But even though I strongly favor these reforms and others, I am even more strongly opposed to the convening of a constitutional convention. At least right now.

A convention in the current political climate could devolve into a potentially uncontrollable free-for-all that could lead to all sorts of dangerous unintended consequences.

Although no such convention has been held in the U.S. since 1787, there's a movement underway to establish one now, and some analysts think it's getting frighteningly close to happening.

Under Article V of our existing Constitution, states are allowed to petition Congress for a convention to propose constitutional changes and emendations. By one count, 19 states have already made such a request, and more than a dozen are moving in that direction. Those numbers are, for a variety of reasons, murky, but if two-thirds of the 50 states — 34 of them, that is — petition for a convention, Congress would have to call one.

What would a convention look like, who would be appointed to it, how many votes would each state get, what would be the rules of engagement? The Constitution doesn't say. Presumably its members would be appointed by state legislatures and would negotiate until they agreed upon a package of proposed constitutional changes. To be adopted, the proposals would require the approval of three-quarters of the states.

So why oppose it? To be honest, my position is less about principle than pragmatic politics. In our current political climate, I fear it could go entirely off the rails.

Although Democrats and Republicans have changes they'd like to see made to the Constitution, it is the GOP that is most feverishly pushing for a convention at the moment. Republicans currently control most of the state legislative seats in the country, and they could have disproportionate power in this process compared with Democrats.

It's even conceivable (though by no means certain) that at a constitutional convention each state would have a single vote, meaning that liberal California, with 40 million people, would have no more say than Republican-dominated Wyoming, with 581,000 people.

Rick Santorum, the former Republican senator from Pennsylvania, is a key backer of the convention, which he says is justified by "the current state of the federal government and the inexorable path toward fiscal disaster and socialist tyranny."

Other proponents, according to a recent New York Times story, include members of the Tea Party, the Federalist Society and lots of Trump supporters.

That's a particularly scary idea at a moment of intense political polarization and animosity, when common ground is elusive, at best, and when disruption, populism and demagoguery are in vogue.

Imagine the excitement of election deniers, climate deniers, immigration opponents, abortion opponents and pro-gun groups at a chance to rewrite the Constitution. Imagine the feverish maneuverings of big corporations and other special interest groups just outside the room.

How bad could it get? Theoretically, very bad. I'm just making this up, but the convention could propose strengthening the Second Amendment, rejecting any restrictions at all on gun ownership. Or it could call for weakening the separation of church and state by making reference in the Constitution to the nation's Christian heritage. Or imposing a national abortion ban. Or removing the First Amendment's protections for the free press.

Oh, that would never happen, you say? I'm dealing in worst-case fantasies? Maybe so.

Some very smart legal scholars think that I'm being histrionic. Sanford Levinson, at the University of Texas at Austin, is no conservative, but he supports a convention because he believes our current foundational document is "radically defective" and that structural change is necessary if government is to work effectively. He believes that extreme proposals like the ones above would never come to pass because they wouldn't win the support of three-quarters of the states.

Even conservatives have opposed a constitutional convention in the past. Chief Justice Warren Burger told Phyllis Schlafly in 1988: "There is no way to effectively limit or muzzle the actions of a constitutional convention." Justice Antonin Scalia told an interviewer: "I certainly would not want a constitutional convention. I mean, whoa! Who knows what would come out of it?"

Yes, we need serious, mature discussion about the Constitution's flaws and how to fix them. The traditional amendment process has become awfully difficult to use, which is why the Constitution has been amended only once in the last 50 years.
