Martha Coakley’s top pollster Celinda Lake has a warning for Democrats, insisting that tonight’s loss is part of an anti-incumbent fever that threatens to take down Democrats across the nation.

“There’s a wave here. The first shore was New Jersey and Virginia,” Lake told CNN Tuesday, referring to Democratic losses in the governor’s races in New Jersey and Virginia. “The second was Massachusetts, and it’s coming to the island now, so we’d better do something about it.”

She added: “We need to understand that angry voters are the ones turning out to vote. Our base complacent. We need to respond to that.
