If Scott Brown wins tomorrow’s special election in Massachusetts, it will be the first time Republicans will have won a U.S. Senate race there since Edward Brooke was re-elected to a second term in 1972. That was the same year Republicans last won a U.S. Senate race in New Jersey – Clifford Case’s landslide re-election to a fourth term against former U.S. Rep. Paul Krebs. Only two other states have gone longer than New Jersey and Massachusetts without electing a Republican to the U.S. Senate: Hawaii, which did it last in 1970, and West Virginia, when Robert Byrd unseated a Republican incumbent in 1958.
