Mr. Bush, for instance, has sent personal letters to the families of every one of the more than 4,000 troops who have died in the two wars, an enormous personal effort that consumed hours of his time and escaped public notice.

The vice president, who has been derided in the media as “Darth Vader,” also has operated outside of the limelight to support wounded troops and their families even though he could have made political hay if he had made them public. He and his wife have hosted wounded troops and their families at his residence at the Naval Observatory, arranging for big-name country singers, such as Charlie Daniels and Sara Evans, to provide entertainment.
