Scott Brown has run an effective outsider’s campaign, with “Man v. Machine” as his key theme. So I found something that Mark highlighted yesterday interesting. Ed Markey congratulated Scott Brown on “uniting the Democratic party.” Not “the people of Massachusetts.” But the party machine. Markey did a good job of underscoring the “Man v. Machine” theme that has catapulted Brown into contention in this race. Not every opposition candidate would be able to harness that disaffection, so Brown gets enormous credit for an effective campaign. But you can’t say that he hasn’t had a lot of help from the united Democratic machine.
