Updated election results showed six-term veteran Democratic state Sen. Cathy Osten was re-elected in the 19th state Senate district over Republican challenger Jason Guidone.

In tallies posted on the Secretary of the State’s website Wednesday morning, Osten received a total of 25,648 votes on three ballot lines, and Guidone received 19,456 votes. Osten was cross-endorsed by the Working Families and Independent parties.

Results were slow in coming late Tuesday, with Osten’s lead increasing slightly as more towns reported numbers.

“I’m overwhelmed by the support of the people of eastern Connecticut,” Osten said Wednesday morning. “There’s much left to be done, and I will work with and for all of my constituents.”

The district covers the towns of Columbia, Franklin, Lebanon, Hebron, Ledyard, Lisbon, Marlborough, Norwich, Sprague, and part of Montville.

Osten, 69, of Sprague, a retired corrections officer for the state Department of Correction and an Army veteran, serves as Senate chair of the key Appropriations Committee and campaigned on her record of securing state funding for district towns.

Osten stayed glued to her laptop and phone at the Democratic gathering point at Jack’s Brick Oven Pizzeria in Norwich as numbers slowly came in ― and didn’t.

Guidone could not be reached to comment late Tuesday.

During the campaign, Osten vowed to continue to support the towns, especially seeking funding for the five distressed municipalities in the district, including Norwich. She has supported Norwich’s efforts to obtain millions of dollars in state grants for waterfront and downtown improvements, to develop a second Norwich industrial park and to boost state reimbursement rates for the city’s $385 million school construction project.

She has been an avid champion of the manufacturing pipeline job training program, with an emphasis on trades education now present in 18 high schools, as well as Three Rivers Community College.

Guidone, 49, of Hebron, retired after 20 years in video production and management at ESPN in Bristol and was running for the first time for an elected office. He is chairman of the Hebron Republican Town Committee.

Guidone hit on major Republican points during the campaign, vowing to curb state spending and bring a new voice to the Democratic-controlled state legislature, calling it “the Democratic mob” in one campaign ad. He pledged to rein in state spending and end what he called the “sanctuary state” policies on immigration.
