The guest list for the 2005 White House dinner honoring the Prime Minister of India, Manmohan Singh, included one “Mrs. Char Lugar, United States Senate Spouse.” It is, of course, a fitting title for a politician’s wife. Lugar, however, brings a special dignity and grace to the job. No wallflower, she bas been a frequent, active participant in the numerous public- and foreign-policy conferences that her husband traverses the country to attend. When he visits or hosts foreign dignitaries, she’s an able, reliable second. And when he ran for the Republican presidential nomination in 1996, she proved to be his best campaigner, championing his positions whenever a tight schedule made it impossible for him to appear. And through all the senator’s many travels and late nights, she’s always been there to hold down the homestead and raise their four sons, Mark, Robert, John, and David.
