District 8
The 8th district includes South Boston and the southern Boston metro area. The incumbent was Democrat Stephen F. Lynch, who was reelected with 98.4% of the vote in 2018 without major-party opposition.

Democratic primary
In the Democratic primary, lawyer and ten-term incumbent Lynch defeated progressive challenger Robbie Goldstein, a medical doctor with expertise in infectious diseases and transgender healthcare. Several weeks before the primary, the Boston Globe noted the "stark contrast" between the candidates on several key issues, particularly healthcare and police reform. A proponent of Medicare for All, Goldstein ran on a platform of expanding healthcare access during a campaign overshadowed by the COVID-19 pandemic. Lynch, who remains one of only three Democrats in the House who voted against the Affordable Care Act in 2009, advocates reforming the current market-based healthcare system. In the context of nationwide protests against police brutality and killing of unarmed black citizens, Lynch stated his support for efforts to modify qualified immunity for police officers, while Goldstein advocated ending qualified immunity outright.

Goldstein's campaign also highlighted differences between the two candidates on LGBTQ issues and reproductive rights. In the past, Lynch has identified as pro-life, a position he now deems too extreme.

Several Democratic primary challengers over the years have called Lynch too moderate to serve Massachusetts's electorate. In 2010, Lynch responded, "Calling me the least liberal member from Massachusetts is like calling me the slowest Kenyan in the Boston Marathon. It's all relative."
