Candidates ;Ran •
Harold Washington, incumbent mayor •
Jane Byrne, former mayor (1979–1983) • Sheila A. Jones He had at one point been widely expected to follow-through on these plans. However, Washington ultimately ran for re-nomination, formally announcing his candidacy on November 30, 1986. Former mayor Jane Byrne (who Washington had unseated in 1983 primary) had already declared her own candidacy by this time. Byrne's campaign ads argued that under Washington's tenure racial tensions in Chicago had increased. Byrne's strategy aimed to limit Washington's share of the white vote to a maximum of 10%, while managing to capture 10% of the black vote for herself. Post-election polling indicated that Washington received 96% of the black vote (a greater share than he had received four years earlier). Polling also indicated that he received 21% of the white vote (more than twice what he had received four years earlier). Surveys also indicated that turnout in heavily black precincts had increased since the last election, whilst turnout in heavily white precincts had experienced a small decline. Also running was Sheila A. Jones, a
LaRouche movement devotee. On January 13 he declared that he intended to instead run as the nominee of the "Chicago First" party, a party which he himself had just founded. He and Edward Vrdolyak opted to prepare for possible third-party runs (with Vrdolyak seeking the
Illinois Solidarity Party nomination) rather than risk Washington benefiting from a three-way split in the primary election similar to the one in the 1983 primary. Hynes (a career-long Democrat) opted to make a third party run after leading Republican operatives persuaded him to do so.
Polls Results Turnout was 75.68%. Washington received 25% of the white vote, rising from 17% he received in 1983. Two reviews conducted by the Chicago Board of Election Commissioners and an election watchdog group headed by former
U.S. Attorney Dan K. Webb found that tens of thousands of ballots were fraudulently cast by ineligible voters. ==Republican primary==
