Karen Breslin is in the news as one of the Democrats running in the primary for Seth Moulton’s House seat in Massachusetts. The race is drawing attention for its focus on affordability, healthcare, and immigration, along with candidates’ fundraising and local support. More broadly, the primary is being shaped by tensions inside the Democratic Party over how strongly candidates should align with national figures and progressive criticism of ties to defense contractors and Israel.
