in the general election, defeating Dennis Block (Republican), Dennis Brasky (Socialist Labor) and Gerald Rose (U.S. Labor). Bilandic delivered his inaugural address and took office on June 22, 1977. However, popular though he was at this time, his term as mayor would prove to be short and difficult. Bilandic had to face several labor disputes while in the mayor's office, including a gravediggers and cemetery owners' strike and a threatened strike by members of Lyric Opera of Chicago. The Chicago Butcher's Union worked to stop stores from selling fresh meat after 6 p.m., but Bilandic managed to work out a settlement. Bilandic also had to face social unrest in June 1977 when an FALN bomb exploded in City Hall and started a two-day riot among the Puerto Rican community. Bilandic oversaw the creation of ChicagoFest, a food and music festival held on Navy Pier. The Chicago Marathon had its first running in 1977 and Bilandic participated, finishing with a time of 4 hours. A runner himself, Bilandic arranged to have five miles of unused equestrian paths along the lakefront converted to running paths. A 1993 survey of historians, political scientists and urban experts conducted by Melvin G. Holli of the University of Illinois at Chicago ranked Bilandic as the twenty-first-worst American big-city mayor to have served between the years 1820 and 1993.

Additionally, as part of attempts to deal with the storm, Bilandic ordered Chicago 'L' trains to bypass many intermediate stops, particularly affecting black neighborhoods on the South Side of the city, and angering that large voter base. 1979 Democratic primary The former longtime head of Chicago's consumer affairs department, Jane Byrne (who was fired by Bilandic in 1977), ran against the mayor in the 1979 Democratic mayoral primary. Besides dissatisfaction with the city's handling of the snowstorm, other issues hindered the mayor's reelection campaign. Republicans voted in the Democratic primary against the mayor in order to defeat the Democratic machine that had dominated Chicago politics for decades. Reverend Jesse Jackson endorsed Byrne for mayor. And North Side and Northwest Side voters voted for Byrne because they were angered by the Democratic leadership's slating of only South Side
