Ayanna Pressley’s win over Mike Capuano was the big national story coming out of Massachusetts’ Sept. 4 primary, but there were some other dramatic developments, too — including Rachael Rollins’ win in the Suffolk DA’s race and the ouster of two members of House leadership — Ways and Means Chair Jeffrey Sanchez and Majority Whip Byron Rushing. Lawyer and activist Nika Elugardo and physician Jon Santiago, Sanchez and Rushing’s victorious challengers, join Peter Kadzis and Adam Reilly to discuss their wins, the change they hope to bring to the House, and who they’ll back in the next election for House speaker.
