Melissa J. Murgo will match up again in the Democratic primary against incumbent state Rep. John P. Fresolo in the 16th Worcester District.

Ms. Murgo, 27, a Worcester native, made her first political run two years. She lost to Mr. Fresolo, for whom she was once a legislative aide, by 621 votes, garnering 43.5 percent of the vote.

Ms. Murgo said that her top priority is public education. “Local schools need governmental support more than ever. Four schools have been closed this year in Worcester,” she said.

Having attended Worcester schools and graduated from Westboro High School, she said she “believes that we need to ensure adequate resources to help all children achieve their potential. This begins by fighting for our teachers and giving them the tools they need to educate our children in a safe environment. We need to fund Chapter 70 fully by fighting the expansion of charter schools.”

The candidate also vowed to focus on property taxes, which she said “have continued to rise and have become too big a burden for many Worcester citizens to handle, particularly seniors.” Ms. Murgo said she would propose or support legislation to freeze the property tax rate for residents over 65 years old.

She also said she places priority on making healthcare more affordable and accessible. Saying that healthcare costs in Massachusetts are the highest in the country, Ms. Murgo said “it is time now to change our health insurance system so that it works for everyone, most importantly our senior citizens. We need to stop making our HMOs and pharmaceutical drug companies richer, while seniors struggle to make ends meet due to expensive prescription drugs and co-pays.”

Ms. Murgo said she supports importing low-cost drugs “as a check on the greediness of the drug companies.”

The operations manager for D. Murgo Trucking of Worcester and Westboro, Ms. Murgo said she also will focus on jobs. “We need to create and encourage job growth in Worcester through targeted economic incentives to small businesses.

“Although the economic boom of the last decade largely bypassed Worcester, the city has become very competitive in the housing and wage markets. Regionally targeted incentives will give companies and businesses the opportunity to keep and create jobs in Worcester,” she said.

Ms. Murgo said, “Today, our state government isn’t doing enough for the working families of Worcester” and she will change that.

She has a bachelor’s degree in political science and communications from Boston College and a master’s degree in public administration from Framingham State College. She has worked in the secretary of state’s office and as an aide in the House of Representatives.
