(CNN) - While several Democrats Wednesday questioned how Massachusetts Attorney General Martha Coakley managed to lose what was expected to be an easy Senate race in the bluest of states, White House Press Secretary Robert Gibbs isn't pointing fingers.
"I don't want to get into the blame game," Gibbs said at Wednesday's White House daily briefing. "I said earlier I think we all bear some responsibilities."
But echoing his own words from earlier in the week, when polls showed Coakley heading for a defeat, Gibbs said "there was a surprise and a frustration here."
While the White House is publicly refusing to assign blame on the Coakley campaign, a top adviser to President Obama on Tuesday rejected assertions that the vote was a referendum on the president or Democratic policies: "Campaigns and candidates matter," the adviser said.
Meanwhile, Coakley's top pollster, Celinda Lake, insisted Tuesday that the loss was 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."
