Will this be a change election in Massachusetts?

A lot of political energy has been unleashed in reaction to Donald Trump’s election two years ago. Nationally, Democrats are hoping it will translate into big gains in the midterm congressional elections, with possibility of taking back control of the House.

In Massachusetts, where Democrats already hold the overwhelming share of elected offices, that energy and the appetite for change is mostly playing out within Democratic primaries, with several longtime incumbents facing serious challenges for the first time in years. The two most prominent races are the 7th Congressional District, where 20-year incumbent Michael Capauno is being challenged by Boston City Councilor Ayanna Pressley, and the race for secretary of state, where 24-year incumbent Bill Galvin faces another Boston city councilor, Josh Zakim.
