How to read this. This page lists every candidate the Delaware Department of Elections shows for this office, in the state's own order, with the same fields for each person: party, filing status, filing date, and campaign website if the state lists one. We publish no home addresses or phone numbers, rank no one and endorse no one. The Department of Elections is the authority; if this page and the state list differ, the state is right and we fix this page. Read the method.

Public positions, in their own words
For too long, Delaware families have watched the cost of housing, groceries, healthcare, and energy climb while Washington has delivered more spending, more debt, and more dysfunction.
Political power belongs to the people. Elected officials only borrow it. Transparency, dissent, and the free exchange of ideas are essential to good government. No party has all the answers.
