It may seem outlandish to launch a campaign broadside by television ad and book flackery devoted to discrediting the respectable Vietnam War record of Senator John Kerry, who has five combat medals. The leader of the attack, John O'Neill, a Swift boat veteran and Texas lawyer, has been a detractor of Mr. Kerry for decades, ever since the Nixon White House recruited him to rebut Mr. Kerry's criticism of Vietnam policy. And the chief donor to the Swift boat broadside is a Texas businessman, Bob Perry, who is known for giving millions to the campaigns of President Bush and other Republicans. Senator John McCain, the Vietnam hero who was smeared by one such "independent" stealth group in the 2000 campaign, has denounced the Swift Boat Veterans' attack as dishonest and dishonorable, declaring, "The Bush administration should specifically condemn the ad." So far that hasn't happened. We can only hope the senator brought the point up as he campaigned last week with Mr. Bush.
