Maybe you’re right. Berkshire 131K; Franklin 71K; Hampden 463K; Hampshire 158K - Total 824K, enough for 1 CD plus 96646 left over. Worcester Co. is 798K+. If the 3rd goes west from Worcester, it could capture Springfield. Then other CD’s would have to mop up the remaining 168K of Worcester County.
That's not going to happen. When you get a Berkshires/Pioneer Valley district that stretches all the way to Route 128, it's not a Berkshires/Pioneer Valley district anymore.
Getting stuck with Springfield would at least keep the Western Mass character of the district.
I'd like to see Barney Frank get thrown in somebody else's district, but I doubt that's going to happen either.
