Sen. Susan Deschambault on Tuesday easily won the Senate District 32 race for the Democratic nominee for the November ballot.

Deschambault, a former Biddeford city councilor serving a partial term in the Legislature, faced a challenge from Joanne Twomey, a former state representative and Biddeford mayor.

Deschambault took 85 percent of the vote. With 10 out of 12 districts reporting, Deschambault had 1,366 votes to Twomey’s 244 votes.

The primary winner will run against Republican Stephen Martin of Biddeford in November. Martin lost a special election for the District 32 seat in March to Deschambault.

Senate District 32 includes Alfred, Arundel, Biddeford, Dayton, Kennebunkport and Lyman.

Deschambault, who was celebrating her victory in downtown Biddeford Tuesday night, said she was humbled by the amount of support she saw at the polls.

“It was wonderful seeing people saying they were there for me,” she said. “I felt like my team was multiplied by 10.”

Earlier this year, Deschambault, 68, won the special election to fill the seat of David Dutremble, a Biddeford Democrat who resigned for personal reasons. When she arrived in Augusta for her swearing-in ceremony, it was abruptly canceled by Gov. Paul LePage in response to Democrats voting against Steven Webster’s nomination to the Maine Unemployment Insurance Commission.

Twomey was certified to run in the primary after a Biddeford resident challenged the validity of the signatures on her nomination petitions. Both Deschambault and Twomey are well-known in Biddeford, where they have been active in local politics for years. Both are running as clean election candidates and have received $10,000 in public campaign funding.

Deschambault, who retired from the Department of Corrections after 43 years, is chairman of the Biddeford Planning Board. She was a two-term city councilor and served on the city’s Police Commission for 12 years. She had been contemplating a run for office when Dutremble resigned.

Deschambault said she spent the weeks leading up to Election Day going door to door in a district that includes coastal homes, farmland and small rural towns. She credits her victory in large part to the supporters who volunteered with her campaign.

“My team of supporters and volunteers catapulted me to victory,” she said. “You can’t do it alone.”

Twomey, 70, is known for her passionate defense of vulnerable Mainers, including children and seniors. That passion has landed her in the news several times, including after an April 2015 incident in which she flipped a jar of Vaseline onto the stage where LePage was speaking. She served two terms as mayor and represented Biddeford in the legislature for eight years.

Twomey’s involvement in politics – including two terms as mayor and eight years in the legislature – has often centered around voicing the concerns of residents who struggle to stay in their homes and pay bills.
