Sometimes 51 percent does not rule. That is one of the lessons of the 14-senator compromise over judicial nominations reached last week. And it is always true in a representative democracy.
Under the unwritten rules of the British Constitution, the prime minister theoretically has dictatorial power. But in fact his power is circumscribed -- by threats of opposition by members of the majority party, by the admonitory force of negative public opinion polls, by the willingness of the House of Lords to block legislation (a willingness more often demonstrated now that Tony Blair has removed the votes of most of the hereditary lords), by the power of the press. Blair wanted Parliament to vote approval of the European Union Constitution. But in April 2004, when it seemed that that might cost him the support of Rupert Murdoch's Sun, he promised to hold a referendum, instead.
So it goes also in America. George W. Bush has not achieved all his legislative successes by narrow votes. His 2001 tax cuts and education bill had support from plenty of Democrats. So did the Iraq War resolution. So did the class action and bankruptcy bills passed earlier this year.
But he has also won some victories by margins as narrow as his own margin in the Electoral College in 2001: the 2003 tax cuts, trade promotion authority, the 2003 Medicare prescription drug bill. Many congressional Democrats and their constituency among voters feel that Bush has achieved policy victories out of proportion to his margin of support. Losing seats in 2002 and 2004, congressional Democrats have lashed out with frenzied opposition to Bush judges and to U.N. ambassador appointee John Bolton.
Politicians always act out of some combination of conviction and calculation. Elements of both contributed to the decisions of seven Republican and seven Democratic senators to pledge to refrain from changing the rule on filibustering judicial appointees and to eschew judicial filibusters except in "extraordinary circumstances."
At issue here, of course, is not so much the confirmation of the appellate judges under attack but the confirmation of any Bush appointees to the Supreme Court. The agreement still leaves Bush under some constraint. His choice will be at risk of disapproval by filibuster if any two of these seven Democrats finds his nominee to be so unacceptable as to constitute an "extraordinary circumstances." But Republicans could still change the rules on filibustering judicial nominees if the three of these seven Republicans who have said they'll vote to change the rules consider the Democrats' objections to be made in bad faith.
