The mystery of the missing trifecta has been solved. Sort of.

In this space last week, it was noted that President Bush often tells audiences that he promised during the 2000 presidential campaign that he would allow the federal budget to go into deficit in times of war, recession or national emergency, but he never imagined he would "have a trifecta." Nobody inside or outside the White House, however, had been able to produce evidence that Bush actually said this during the campaign.

Now comes information that the three caveats were uttered before the 2000 campaign -- by Bush's Democratic opponent, Vice President Al Gore. The Post's Glenn Kessler found in the archives this promise from Gore: "Barring an economic reversal, a national emergency, or a foreign crisis, we should balance the budget this year, next year, and every year." Gore said that to the Economic Club of Detroit in May 1998, then repeated it at least twice more, in speeches in June and November of that year.
