Three important pieces of information are still missing from the picture required for the American public to evaluate the remaining candidates for president.

The putative Republican nominee, Sen. John McCain, has not yet made available his current health records. This is important if only on the basis that, if elected, he would be the oldest president to take office. It is also relevant because Mr. McCain has had surgery for skin cancer. Decades earlier, he required serious physical repairs and other therapy after six years as a prisoner of war in Vietnam.

Another area where Mr. McCain owes greater disclosure is personal finances. He has revealed his own tax records, but his wife, who has a considerable fortune that includes inheritance from her father's beer distributorship in Phoenix, has declined to make her returns available for public consideration.

It is true that since the McCains file separate returns, she is not required by law to reveal her financial status. At the same time, applicants for federal positions must submit their financial records and that of their spouses to the government's ethics overseers for examination for possible conflicts of interest.

The third missing piece from the public campaign file involves Sen. Hillary Rodham Clinton. The Clintons have revealed their tax returns, but they have not yet told the public who contributed to the presidential library in Little Rock, Ark., and how much. Assuming that Mrs. Clinton continues to remain a candidate for the Democratic nomination, it is far past the time when the Clintons should have made this information available. Continuing to hold out only feeds speculation that the list contains the names of people who might cause embarrassment or whose contributions would be seen as embarrassingly large and unduly influential.

Voters need to know the state of Mr. McCain's health, how much money his wife has and who contributed how much to the Clinton library. This information should have long ago been on public record. For the candidates to keep Americans in the dark raises the question of what they don't want us to know.
