In 1992, Jacobs announced that she would run for the State House, though there was initially uncertainty around which districts would be drawn in
Palm Beach County, and which incumbents would run where. She faced lobbyist
Anne M. Gannon and former Delray Beach City Commissioner Jimmy Weatherspoon in the Democratic primary. Jacobs placed first in the primary, winning 49 percent of the vote to Gannon's 31 percent and Weatherspoon's 20 percent, but because no candidate won a majority, a runoff election took place. Jacobs led in the runoff election by 22 votes, but Gannon refused to concede, and instead waited for an automatic recount to take place. After the recount narrowed Jacobs's margin to 21 votes, Gannon sought a partial hand recount, which affirmed Jacob's victory. Gannon sought to contest the result, arguing that the Supervisor of Elections gave her incorrect mailing labels for her campaign literature, which caused her to send information to voters outside of the district and missed 64 voters inside the district. Gannon ultimately dropped her challenge and conceded the race. Jacobs proceeded to the general election, where she faced Republican nominee Curt Mondell, a paving contractor who had been arrested for domestic violence earlier in the year. Though the
state Republican Party targeted the race, Jacobs won in a landslide, receiving 62 percent of the vote. In 1994, Jacobs ran for re-election for a second term and faced a rematch in the Democratic primary with Gannon. In a close race, Jacobs narrowly defeated Gannon, winning 51 percent of the vote to Gannon's 49 percent. In the general election, Jacobs was challenged by attorney Carl Cascio, the Republican nominee. Jacobs won re-election in a landslide, winning 63–37 percent over Cascio. Jacobs ran for re-election to a third term in 1996, and was challenged by independent candidate Thomas Widom. She defeated Widom with 75 percent of the vote. In 1998, Jacobs was challenged in the Democratic primary by attorney Chris Anstead, the son of
Florida Supreme Court Justice
Harry Anstead, and
Palm Beach County Democratic Party Chairman Greg Nicosia. Jacobs won renomination by a wide margin, receiving 65 percent of the vote to Anstead's 23 percent and Nicosia's 12 percent, and won her fourth term automatically, because no other candidates filed. Jacobs was term-limited in 2000 and could not run for re-election to a fifth term. Jacobs died on March 18, 2020, at the age of 83. ==Post-legislative career==
