Eugene J. McCarthy, the sardonic Senate dove who stunned the nation by upending President Lyndon B. Johnson's re-election drive amid the Vietnam War turmoil of 1968, died early yesterday. He was 89.

A courtly, sharp-witted presence in capital politics for half a century, Mr. McCarthy, a Minnesota Democrat, died in his sleep at an assisted-living home in the Georgetown neighborhood of Washington, where he had lived for the last several years.
