Now that Boston Mayor Marty Walsh is headed to Washington, you can’t swing a stick without hitting a potential mayoral candidate. But when Walsh’s plans were unclear, just two people had the guts to commit to running against him if he sought a third term — and Boston City Councilor Andrea Campbell was one of them. In this episode of the Scrum, she talks with Peter Kadzis and Adam Reilly about Boston’s progress in the Walsh years and what she would do differently as mayor. Campbell also speaks in depth about her twin brother, Andre, whose death in pretrial detention had a massive impact on the way she thinks about Boston politics.
