BOSTON-In a political stunner, incumbent Democratic U.S. Rep. Michael Capuano lost Tuesday's primary to Ayanna Pressley, a Boston city councillor who is virtually assured of becoming the first black woman to serve MA in Congress.
Keating will take on Republican Peter Tedeschi in November.
The win means Lynch, first elected in 2001, is virtually ensured another two-year term in the 8th Congressional District.
She received a number of high-profile endorsements, including from the Boston Globe and Alexandria Ocasio-Cortez, the democratic socialist who enjoyed a similar victory over Rep.
Pressley represents the latest underdog candidate to have emerged to challenge both establishment Democrats and Republicans.
"Our president is a racist, misogynistic, truly empathy-bankrupt man", Pressley, 44, told supporters on Tuesday night.
But both Pressley and Capuano admit there's likely no difference between them in terms of the way they'll vote in Congress, and moreover, neither one has expressed outright opposition against Democratic leader Nancy Pelosi.
Pressley's win echoed that of Alexandria Ocasio-Cortez's over the long-time representative Joe Crowley in NY, and the ascent of Stacey Abrams in Georgia, who - if she wins - will become the first African-American female governor in USA history.
Later during Pressley's victory party, her stepdaughter Cora stood in silence with tears rolling down her face as she listened to Pressley speak.
Pressley conceded throughout the race that there was little policy daylight between her and Capuano, though she did go further than him by calling for the abolishment of the Immigrations and Customs Enforcement agency.
"When I was growing up, my mother and I felt voiceless and invisible, but she made sure I knew that on Election Day we were powerful", she said during her speech.
Massachusetts' last Democratic primary upset came in 2014, when Seth Moulton defeated Rep. John Tierney in the state's 6th Congressional District.
