Four of the more interesting primary contests remaining take place Tuesday in Massachusetts. These are all Democratic contests in safely blue seats; the primary winners will be prohibitive favorites in the general election.
Polls close at 8:00 PM Eastern Time. Live results will appear below after that time.
Senate: Sen. Ed Markey is seeking a third term. He is being challenged by Rep. Joe Kennedy III (MA-04). Something has to give. As the Washington Post notes, "Markey has never lost an election in his 47 years of public service, but no Kennedy has ever lost an election in Massachusetts." Kennedy led in the polls earlier this year but more recent polls have swung strongly in the incumbent's favor. Markey currently has an 11 point lead in the Real Clear Politics average.
