Massachusetts took a big step towards expending the gambling industry recently when the Senate passed a bill that would legalize sports betting---but there are some huge and potentially irreconcilable differences between the Senate plan and the one the House passed last year. Adam Reilly spoke with Shira Schoenberg, a reporter at Commonwealth magazine, and Father Richard McGowan, S.J., an associate professor of finance at Boston College's Carroll School of Management, about those discrepancies and whether a compromise is likely. Also: campaign finance is taking center stage in two Democratic primaries, as AG candidate Quentin Palfrey calls on his opponents to reject Super PAC spending and Sonia Chang-Díaz urges Maura Healey to return donations from individuals linked to the fossil-fuel industry in the governor's race. The Boston Herald's Sean Phillip Cotter and GBH News's Saraya Wintersmith joined Adam to discuss those calls, former state Senator Dianne Wilkerson readying a run for her old seat, and more.
