I just wrote a post on the Mass. Numbers blog looking retrospectively at the Markey/Lynch polls from January through April.

It is really striking how closely they converged to the eventual result. Public Policy Polling gets a special shout out for just about nailing it in their last poll.
It makes sense to take the early polls of the Markey/Gomez matchup with a grain of salt, but the surveys will likely be more accurate as we approach the June 25 election.
