Where things stand

Relay Note

Democrat Troy Jackson won Maine’s U.S. Senate seat, defeating incumbent Republican Susan Collins, a five‑term senator who has served since the late 1990s, according to reports from NPR and CBS News. Jackson, a former Maine state senate president, secured the victory that one newsroom says is crucial for Democrats to retake the Senate majority. The Guardian and NPR differ on Collins’s length of service, with the former noting she began in 1997 and the latter describing her tenure as “nearly 30 years.”

What the win means for the Senate’s overall balance of power and what policy priorities Jackson will pursue remain unanswered, as the reports do not explain how his new seat will affect party dynamics.
