Edward H. Deavitt holds a law degree from Harvard Law School and graduated from the University of Vermont. He began his career in public service, serving as a member of the state board of bar examiners and a bankruptcy referee. Deavitt transitioned to elected office, serving as State Treasurer and later as Mayor of Montpelier. His leadership roles also included serving on Montpelier's City Council and as Speaker of the Vermont House of Representatives. Post-public service, he resumed business interests, holding executive positions in various companies and serving as President of the Green Mountain Mutual Fire Insurance Company.

Edward H. Deavitt's political philosophy is marked by a steadfast commitment to limiting executive power, as evidenced by his advocacy for the "Mountain Rule." His approach to governance is deeply rooted in a belief in localized control, which he consistently applied across various roles from state treasurer to mayor. Deavitt's business acumen and his leadership in local industries suggest a unique blend of public service and private sector experience, raising questions about how he reconciles these roles in his policy-making. His challenge to the incumbent governor's stance on the "Mountain Rule" during a period of crisis reveals a willingness to confront conventional wisdom, hinting at a calculated and perhaps contrarian political strategy.
