Leading Off
●MA-01: Democratic Rep. Richie Neal earned a high-profile endorsement from an unlikely source as Massachusetts' Republican governor, Charlie Baker, waded into Neal's hotly contested primary battle with Holyoke Mayor Alex Morse on the same day that a new poll found the congressman leading his challenger with just days to go.
On behalf of the news site Jewish Insider, a survey from RABA Research put Neal up 49-40 on Morse ahead of Tuesday's primary. That result was not far off from the only other poll we've seen of the race, a mid-August Morse internal from Beacon Research that had Neal ahead by a 46-41 spread.
