A year after conservative Justice Samuel Alito succeeded liberal-leaning Justice Sandra Day O’Connor, a disagreement between two of the nation’s best legal journalists about how much President Bush has transformed the Supreme Court prompts this challenge to Court-watchers:

What will the legal landscape look like in 10 years? Make your predictions and place your bets.

In a widely acclaimed book full of revelations about behind-the-scenes battles over the Court, Jan Crawford Greenburg, now of ABC News, says that after decades of disappointment, conservatives have finally won the day. The appointments of Alito and Chief Justice John Roberts will produce a "profound and lasting alteration," Greenburg writes in Supreme Conflict: The Inside Story of the Struggle for Control of the United States Supreme Court. They and their allies will now engineer "one of the most fateful shifts in the country’s judicial landscape in a generation … with repercussions as yet unimagined," she predicts.

"I’m not holding my breath," retorts Benjamin Wittes in The New Republic Online. Wittes, an author and a guest scholar at the Brookings Institution who until recently wrote the nation’s smartest legal editorials for The Washington Post, highly recommends Greenburg’s book (as do I) for its "genuinely spectacular" reporting. But he dissents from her view that Bush has set the stage for an era of conservative hegemony.

To advance this intriguing discussion, I offer specific predictions below and invite others to offer theirs.
