Patrick Dempsey says he will not run to replace Graham Platner as the Democratic nominee for the US Senate in Maine after Platner suspended his campaign amid multiple misconduct allegations, including denied sexual assault claims and allegations of non-consensual condom removal.Dempsey writes in the Portland Press Herald that he seriously considered a bid but concluded he can make a greater difference through the Dempsey Center and community work that addresses rising living costs, the disappearance of local industries and healthcare affordability.Maine Democratic leaders must select a replacement nominee by July 27; Dempsey's decision removes a high-profile contender and shifts the debate to the party's selection process and the larger questions facing Maine voters.
