There's an interesting analysis on Blue Mass Group:

You can download a spreadsheet from there.

In a nutshell, they looked at the vote percentages of Healy/Patrick and compared them to Bush/Kerry 04, compared to the statewide average (that's the key part).

Healy's percentage vote in Chelmsford was 10.6% better than her state average, Deval's was 10.8% lower.
Bush's percentage vote in Chelmsford was 9.3% better than his state average, Kerry's was 9.4% lower.
...which basically confirms Chelmsford is a more red town than the rest of the state.

When you subtract the Bush/Kerry 04 numbers from the last election, you get 1.4% for Healy. In other words, Chelmsford was 1.4% more red in this election than it was in the 04 election.

Then consider the votes the extremist Martinez drew against Fargo. 45% to 49%... How could it have even been that close?

When you consider our effort against the Healy effort... wow. Is Chelmsford really turning deeply red, and we're just slowing it down?
