6:00 Update
61,090 votes through 6:00pm, so still on target for roughly 75,000. Voting is strong in Southie, Eastie, West Roxbury, Savin Hill area. There seems to be a little life in the Grove Hall/Franklin Field/Fields Corner sections of the black community. Not so much in Roxbury, despite the Chuck Turner primary. Worst of all: areas thick with younger, whiter, professional-class progressives. Back Bay, JP, Fenway, Allston-Brighton from BU to Cleveland Circle, South End, Beacon Hill... pathetic lowly numbers.
What will this all mean? We'll start to find out in a little while. Polls close at 8:00.
I'll be tweeting as much as possible the rest of the way, but probably not blogging here until late. So if you want to follow me tonight, catch me on Twitter (@dbernstein)!
