Tuesday is preliminary election day in Massachusetts, and if you had no idea, you’re probably in the majority.

One of the communities coming out to vote will be Boston, where the race for mayor and four city council spots will be narrowed down to two candidates each. Of the 391,000 registered voters in the city, about 60,000 (15-percent) are expected to cast their ballots – setting up a major challenge for candidates looking to churn out support, especially among younger voters.

Ashley Spillane, former president of Rock the Vote, who knows a thing or two about the challenges of getting people to the polls; and Joe Slade White, a long-time strategist for former Vice President Joe Biden and now a visiting fellow at Harvard’s Institute of Politics working with students on voter engagement issues, joined Jim Braude to discuss the best approach to mobilizing a young voter.
