The 1990 Massachusetts gubernatorial election was held on November 6, 1990. Incumbent Democratic Governor Michael Dukakis, his party's nominee for president in 1988, opted to not seek a fourth term. Republican Bill Weld won the open seat, beating Democrat John Silber to become the first Republican Governor of Massachusetts elected since 1970. Democratic primary Governor Candidates Francis Bellotti, former Lieutenant Governor and Attorney General of Massachusetts John Silber, president of Boston University Eliminated at convention John H. Flood, State Representative from Canton Withdrew Evelyn Murphy, incumbent Lieutenant Governor Declined Raymond Flynn, Mayor of Boston Michael Dukakis, incumbent Governor Campaign After Flynn's decision not to run, Murphy was the early frontrunner due to her strong name recognition and a solid base of liberal support. In July 1989, she led Bellotti 42% to 18% in a Boston Globe poll. That November, Bellotti had come within 2% of Murphy in another Boston Globe poll. In January, Silber entered the race and Bellotti ran his first wave of television ads. By this point, Bellotti had taken the lead in the race, polling 38% to Murphy's 20% and Silber's 16%. The Democratic Convention was held on June 2, 1990 at the Springfield Civic Center. On the first ballot, Bellotti received 42.9% of the vote, Murphy received 37%, Silber received 15.5%, and Flood received 4.5%. Silber's 15.5% gave him enough votes to remain on the ballot. On the second ballot, Bellotti won the convention with 51%, Murphy received 40%, and Flood received 8.5%. Flood was not able to stay on the ballot as he did not receive the necessary 15%. Murphy's campaign appeared to be badly hurt by the public perception that she was close to the unpopular Dukakis and therefore tried to make a break with the Dukakis Administration. Dukakis twice postponed a trade mission to Europe because Murphy hinted at a news conference that she would execute her own economic plan while serving as acting governor. After the incident, Murphy's unfavorable rating rose to 49% in a Boston Globe/WBZ-TV poll, compared to 38% a month earlier. A week before the primary, Evelyn Murphy dropped out of the race and threw her support to Bellotti. Results Despite having Murphy's support and as high as a 15-point lead in the polls at one point during the campaign, Bellotti was upset by Silber, a political outsider who had run a provocative campaign filled with controversial statements known
