From CQ Politics:

Tom Jensen offers a preview of a forthcoming Public Policy Polling survey in the Massachusetts race for U.S. Senate: “This has become a losable race for Democrats — but it could also be easily winnable if Coakley gets her act together for the last week of the campaign. Complacency is the Democrats’ biggest enemy at this point and something that needs to be overcome to avoid a potential disaster.”
The final results of the poll should be out this weekend.
