Suffolk pollster David Paleologos has selected Waltham as his bellwether community, and the news is pretty good for Deval Patrick. Suffolk has Patrick ahead in that community by a 47% to 40% margin over Charlie Baker, with Tim Cahill at 9% and Jill Stein at 1%,with 3% undecided. The bellwether results in the Scott Brown race were pretty close to reality. More good news from a polling perspective for Governor Patrick.
