Charles Franklin from National Journal’s Pollster.com has an excellent aggregate analysis of the Massachusetts polling data from the last few weeks, just got a chance to digest it. The upshot is that when all the polls are taken as one — big and small, partisan and non-partisan, public and internal — the trend is resoundingly in Scott Brown’s favor.

Scott Brown’s average lead over Martha Coakley was 8.8 points as of Sunday night. Among only non-partisan polls, Brown’s lead was 6.8 points. Among Democratic polls, 6.5 points. Among Democratic polls including internal Coakley leaks: 3.8 points.

Franklin warns that the polling data in the race is more variegated than usual (half of the polls fall outside +/- 5 points from the trend line), as there are a smaller number of polls than you’d find in a general election, and worries that the race could prove as unpredictable as NY-23 in November (Pollster’s last analysis had Hoffman up five points). But it is hard not to see significance in these numbers.
