The future direction of the Supreme Court is very much at stake in this November’s presidential election. The two or three justices most likely to depart the Court over the next four years -- Justice Stevens, Justice Ginsburg, and possibly Justice Souter -- are liberal judicial activists who routinely read their own policy preferences into the Constitution and who selectively regard their own favored precedents as sacrosanct. If a President Obama or a President Clinton names their successors, the slender operating majority on the Court for liberal activist results on most contentious political issues is likely to be preserved for at least another generation. By contrast, a president committed to nominate, and fight for, justices who will practice judicial restraint offers real hope that the Court may soon be restored to its proper role in our constitutional system. In his speech today, John McCain has provided encouraging evidence that he would be that president. One speech, of course, does not a campaign -- or a Supreme Court appointment -- make. John McCain needs to continue to make the case for judicial restraint and to draw the stark contrast between his views and his Democratic opponent’s on the proper role of the judiciary. If elected, he will need to populate key judge-picking positions -- including the White House counsel and the attorney general -- with experienced advisers committed to his stated goals. (We would rest easier if he threw out a few names now.) And he will need to be ready to devote a lot of political capital to defeat intransigent Democratic opposition in the Senate. Conservatives, for their part, need to do what we can to help McCain live up to his promises.
