I am sure many of you saw the Globe article about redistricting.
(http://www.boston.com/... ) Basically, it said they would combine Olver and McGovern's districts and then create a Cape, Island, Fall River, New Bedford District which either Keating will move to or Frank will move to. Who moves there basically depends on what Keating does, because as Norfolk DA before, he has a home in two districts. If he chooses to run there, Lynch takes the Quincy/Southie district and Frank stays in Newton. If Frank moves down to the Coast, Keating flips over to his original home in Sharon and takes the Norfolk based district. There isn't election data for Mass, but I tried to solidify each district as much as possible, but I suppose both the Lynch district and the Newton/West Norfolk districts could be competitive, but I am not sure. Here are some maps:
Olver/McGovern get a district that is Worcester, Northhampton, Amherst and a lot of the liberal towns out west.
Neal gets Springfield, some of the conservative towns near Foxborough. Tried to give him a little of the west of Springfield area to make sure PVI not too low.
Tsongas keeps the Merrimack valley.
Tierney keeps pretty similar district, Essex County plus some of the Wakefield area.
Markey keeps a pretty similar district, goes from Malden area through Waltham to Framingham.
Grey district has Brookline, Newton, Wellsley, Needham and the Southern end of Lynch's current district in Western Norfolk.
Capuano's district is 49.9 white (total, not VAP). I gave all the minority-heavy areas of Boston, while giving the predominantly white areas to Lynch. Capuano gets Cambridge, Somerville, Downtown Boston, Allston/Brighton. Lynch gets Southie, Jamaica Plain and Quincy.
