Former prosecutor Lisset Hanewicz will succeed Darden Rice on the St. Petersburg City Council after winning election to the District 4 seat Tuesday night.

Hanewicz collected 56% of the vote, making her victorious against opponent Tom Mullins, who garnered 44% of the vote, according to early results from the Pinellas County Supervisor of Elections Office with 51 of 92 precincts reporting.

Hanewicz previously worked for the Pinellas-Pasco State Attorney's Office as a prosecutor. She also served as an Assistant U.S. Attorney with the Department of Justice for the Middle District of Florida.

The new-elect left her law practice in anticipation of her first child. Two years later, she took on a new role as the Crescent Lake Neighborhood Association president, where she worked to revitalize the group. The work, according to Hanewicz, is what prompted her to run for City Council.

Hanewicz ran a progressive campaign focused on affordable housing, environmental protection and sustainability. She raked in endorsements from several City Council members, Democratic leaders and progressive organizations and unions.

Her wide win comes after a tough campaign against Mullins, a Raymond James executive who's campaign had deep pockets — the District 4 race saw the largest campaign funding outside of the city's mayoral election.

Despite leading throughout the the Primary race, Hanewicz's edge was quickly wiped out in the runoff, when Mullins, pulling from his own bank account, gave himself a $236,100 boost in campaign funding, including cutting a $90,000 check just two weeks before the election.

Hanewicz, on the other hand, primarily relied on individual donors and Democratic organizations for funding, although she too contributed $5,000 to her campaign when she launched it.

As of the latest available campaign finance filings, submitted Oct. 29, Mullins collected $259,355, including the self-contributions, while Hanewicz has raised $121,139, including her $5,000 in self-funding.

But, despite his funding boost, Mullins was unable to win over a city with a strong Democratic advantage. Although the municipal elections are nonpartisan, meaning party affiliation does not appear on the ballot, Mullins ran as a vocal fiscal conservative.

Mullins has been an executive with Raymond James since the late 1980s, leading the firm's investment banking practice for the transport and infrastructure industries.

Mullins' campaign was not immune from controversy — the candidate came under fire from local union officials for campaign mailers sent in August, which critics alleged attacked first responders and their unions.

Hanewicz publicly condemned the mailers, pointing to a quote credited to Mullins that smears public worker unions, as well as a blurb from his campaign site, which says city employees are overcompensated "above private-market benchmarks."

However, Mullins fought back, telling Florida Politics he does support police, including providing appropriate funding for such departments. He also said the mailers were misinterpreted, and his conclusions came after meeting with several public employee unions.

The pair advanced to the General Election runoff out of a five-candidate pool. Hanewicz won big in the districtwide election, garnering 42% of the vote, while Mullins took 23%, according to official results from the Pinellas County Supervisor of Elections office.

Hanewicz will take office on the January 6, and will hold a four-year term.
