So, it begins again — that Groundhog Day like process [3] of trying to convince Democrats who are unhappy with the party’s nominee to support the party anyway. And, as always, one of the prime reasons we’ll give this year is the threat a Republican victory would pose to the Supreme Court. At age 53, I’ve seen this dance preformed for 40 years, though with varying degrees of artistry and success.

I’ll touch on only the two most painful examples.

The year was 1968. The Vietnam War [4] was tearing America apart. In March, President Johnson stunned the nation by announcing he wouldn’t seek reelection [5]. There was “division in the American House,” he said, and he was withdrawing in the interests of “national unity.” In April, Martin Luther King was assassinated [6], followed, in June, by the assassination of Robert Kennedy [7].

At the Democratic convention in August, Mayor Richard Daley ordered a police crackdown on antiwar protestors. As the nation watched on television, the streets of Chicago erupted into chaos.

Hubert Humphrey [8], Johnson’s Vice President, became the Democratic nominee. An authentic hero of American liberalism, Humphrey was, nevertheless, constrained by his status as Vice President from openly breaking with Johnson on the war. This made him unacceptable to many doves.

In the emotional aftermath of the convention, far too many liberal voters seemed to accept George Wallace’s assertion [9] (while obviously not accepting Wallace himself) that there was not a “dime’s worth of difference” between Humphrey and Richard Nixon. And they refused to support Humphrey.

I remember how, already a political junkie at age 13, I stood in front of the television screaming at those would-be liberal rebels on the screen: “But what about the Supreme Court?!”

Nixon had been campaigning on a pledge to appoint “strict constructionists [10],” which then, as now, were code words for ultraconservatives, to the Supreme Court. And even at age 13, I understood, at least a little, of what that would mean.

Bit by bit, many of these disgruntled liberals came around to supporting Humphrey, but he lost precious time. And given the closeness of the final result [11], this probably gave the election to Nixon.

And then as payment in full for their “noble” refusal to support Humphrey, these disgruntled Democrats received the Burger Court, four more years of the Vietnam War, enemies lists, the politics of polarization, Watergate and so much more.

Vote for Nader [12]:

Ah, the Supreme Court! Never mind that pro-choice Justice O’Connor was a Reagan appointee or that Clinton’s man Breyer is one of the most economically conservative Justices around–the Supreme Court gets dragged out every four years to squash any attempt to escape the Democratic Party.

A lot of other Nader supporters said similar things, and, without a doubt, Ralph Nader’s candidacy, along with many other factors, helped to put Bush in the White House.

And, yes, Nader voters had every right to vote as they pleased, and the election of Bush was not their fault. No one in America owes his or her vote to anyone else. But looking back is still a wise thing to do, especially when doing so may help to enlighten us in decisions yet to be made.

So what does all of this mean in terms of the decision Clinton supporters will soon have to make as to whether to support Obama?

One thing seems incontestable: as of today, in 2008, as opposed perhaps (although I don’t think so) to 1968 and 2000, there is simply no room left for debate [13] regarding the importance of the election’s outcome to the future course of the Supreme Court. We’ve seen how far George W. Bush was able to move the Court to the right with just two appointments — turning a conservative, but occasionally unpredictable, court into a dependable right wing organ.

Following Bush’s appointment of Roberts and Alito [14], conservatives now stand just one appointment away from achieving their number one political goal of the last 40 years — installing a Supreme Court majority made up of five politically motivated right wing judicial activists. Five Justices who can be depended upon to always come down with the “right” — as in far right — decision.

Think of what that would mean: a Supreme Court made up of five Alitos. Such a Court would literally rewrite the genetic code of our jurisprudence. Overruling Roe v. Wade [15] — which would, of course, be a given — would be only a small start. Progressive legislation would be mowed down as unconstitutional as a matter of course, corporate power enhanced, civil liberties restricted and democracy itself junked through the stripping away of the few remaining limitations on the power of wealth to game the process.

And since these actions would often be taken on the basis of constitutional adjudication, they would be extraordinarily hard to remedy.

If there’s such a thing as a judicial apocalypse, this would be it.

Back in 2000, Nader supporters often accused those of us who warned of what might happen to the Supreme Court if Bush won of crying wolf — in other words, of exaggerating the threat as a means of extorting voters into voting for Gore.

Well, whatever else angry Clinton supporters may say this year to justify opposing Obama, surely we won’t hear that one again. Because we already know how much damage far right appointments can do. Bush has been “kind” enough to teach us. And given that McCain is promising more of the same if he’s elected, there isn’t much doubt [16] what’s on the line.

It ain’t just crying wolf when half the sheep have already been eaten. By then, it should be pretty clear to everyone how much is at stake.
