The Scrum is on hiatus through Boston’s final mayoral election, in part because we’re doing a limited-run show on Boston’s mayoral race, “Boston’s Race Into History.” You can watch it Fridays at 7 pm on GBH Channel 2, or find it at GBHNews.org or on YouTube — but we’re also going to post the audio of episodes here. Video doesn’t work for everyone, and we want as many people as possible to hear what Saraya Wintersmith, Adam Reilly, Peter Kadzis, and other contributors have to say on politics and policy as Election Day approaches. In this episode, we’re sizing up Annissa Essaibi George and Michelle Wu’s contrasting approach to the affordable-housing crisis in the city. Next time, we’ll look at how the two finalists stack up on Mass & Cass, addiction, and homelessness.
