stomv made an excellent point about election result maps by percent: A geographically large town with a large percent margin of victory looks like it had a lot of impact, even if the population is small. What matters ultimately is number of votes, not number of towns or size of the town.
So here’s my map of victory margins by raw vote total, not percent, per community. If you click on the map it will take you to an interactive version on Google where you can click on a city or town and see the details. Sorry about the map legend showing a maximum of 80K difference — that’s the total margin of victory in the state, not one community, but I don’t want to re-do the whole map to fix that. Color scheme goes from purple (Lynch) to green (Markey) — no reds and blues 🙂
