Melecio was part of a four-candidate Democratic slate that swept all four open seats in November 2025, defeating two Republican incumbents and ending a turbulent year of board infighting and nearly $200,000 in legal bills from harassment investigations. The sweep shifted the board from Republican to Democratic control in a traditionally conservative Lehigh County district.
Cross-filed on both party ballots in the May 2025 primary, receiving 1,885 Democratic votes and 288 Republican votes. In the November general election, the Democratic slate's lowest vote-getter finished 527 votes ahead of the best-performing Republican (Stephen Maund). Endorsed by Run for Something (August 2025), Pennsylvania Education Association PAC (PACE), and Southern Lehigh Community Partners PAC. Seated December 2, 2025 and unanimously elected board Treasurer. Not up for re-election until November 2029.
