I feel sad about the 60%-40% defeat of Senator Richard Lugar in Indiana’s Republican primary yesterday. He had a mostly conservative record over the years, fighting the unions’ bill to give them more bargaining power soon after he was first elected in 1976. On foreign policy he chaired the Foreign Relations Committee in 1985-87 and 2003-07 and has been ranking Republican since then. He played an important positive role in forcing out Philippine President Ferdinand Marcos during his first stint as chairman and since the 1990s he has doggedly worked for the Nunn-Lugar effort to corral loose nukes in the former Soviet Union and elsewhere.
