PARTY STAFF
May Hanlon
EXECUTIVE DIRECTOR
May joins the VDP as Executive Director after a career dedicated to building winning campaigns at the local, state, and national levels. A native of Island Pond, Vermont, May began her political work with the Vermont Public Interest Research Group (VPIRG), where she built grassroots support for critical public interest issues and deepened community engagement across the state.
Most recently, May served as Deputy Director of Direct Marketing at the Democratic National Committee (DNC), overseeing key strategies and operations for the Harris Victory Fund. Prior to that, she worked with the Pennsylvania House Democratic Campaign Committee (PAHDCC), where her data-driven electoral strategies helped flip a net of twelve seats in 2022, securing the first Democratic majority in over a decade. She went on to lead the campaign plan for the 2023 special elections, ensuring Democrats defended their state House majority.
May’s experience in both organizing and campaign strategy has reinforced her belief that elections are about more than candidates—they are about long-term movement building and empowering communities. She is eager to strengthen the VDP’s infrastructure, invest in grassroots organizing, and elect Democrats up and down the ballot. A graduate of Bryn Mawr College, May is excited to return home to Vermont and get to work for the people of the Green Mountain State.
