Scott Lively's 27 percent showing at the Massachusetts Republican state convention demonstrates that the hard right is a force to be reckoned with. That it took two ballots for Trump-supporting U.S. Senate candidate Geoff Diehl to clinch the GOP endorsement shows that the Trumpians are not muscle bound, well, at least not ripped. An exhausted but ebullient Diehl joined the Scrum minutes after the convention was gaveled to its close. Other guests include: Michael Jonas of Commonwealth Magazine, Republican delegates Ed Lyons and Amy Carnevale. And from the WGBH political team: Antonio Caban, Mike Deheen, Adam Reilly, and Peter Kadzis.
