"Empathy" is the latest code word for liberal activism, for treating the Constitution as malleable clay to be kneaded and molded in whatever form justices want. It represents an expansive view of the judiciary in which courts create policy that couldn't pass the legislative branch or, if it did, would generate voter backlash.

There is a certain irony in a president who routinely praises America's commitment to "the rule of law" but who picks Supreme Court nominees for their readiness to discard the rule of law whenever emotion moves them.

Mr. Obama understands the danger of heralding Judge Sotomayor as the liberal activist she is, so his spinners are intent on selling her as a moderate. The problem is that she described herself as liberal before becoming a judge, and fair-minded observers find her on the left of the federal bench.
