Mr. Hub Blog – Here is a link to what I think is the most comprehensive list of contested legislative races via Red Mass Group, which tends to do a better job keepings up with these things than Boston media -

As far as the 10th Congressional race goes - only ONE town in the district - Hanover - is represented by two Democrats now (many have Republican representation already, and most of them have no announced challengers) that do not have a challenger for the House or Senate races. I would suggest that this level of local activity will drain away some of the usual enthusiasm for keeping the Congressional seat.

I would also suggest that concentrating on Joe Malone instead of Jeff Perry (who had about 500 people at his kickoff party last Friday, but has the temerity not to live within comfortable coverage range for Boston media) - you may be missing the 'Scott Brown' candidate in the race. ...

PS - I am aware that Sen. Morrissey's challenger is an independent rather than a Republican, but a race is a race. I am also aware of some as-yet-undeclared Republicans in some races that seem uncontested, but my assertion about Hanover is based on the list of announced candidates.
