It seems odd, but for John McCain it was a blessing to have the chance to bury questions about his dealings with lobbyists beneath an alleged sex scandal. The prurient part of the story was easy to deny, and voters are sick of sex scandals.But even if the sex goes away, the underlying questions raised last week in the story for which the New York Times took such grief are unlikely to disappear. The McCain campaign’s sweeping denials may have been a bit too sweeping, and sex, in the end, is not what the story was really about.
