One Democratic strategist said that by Saturday evening he and other surrogates were considerably less worried about the impact of Comey’s letter in large part because Clinton’s response had boosted their confidence.

The strategist, who spoke on condition of anonymity, said while Democrats still aren’t sure what Comey is up to and whether there’s anything new or damaging in the e-mails, the impact for Clinton may be minimal. Still, it could complicate the Democrats’ ability to win back control of the Senate.

He said there remains residual anger among Democrats about Clinton’s use of the private e-mail server while Secretary of State and her slow handling of the controversy in the first place. The shift in approach now has helped offset that anger, he said.

He also said there is a pervasive sense that most voters have made up their minds about the e-mail scandal and that the key for Clinton now is to keep energizing Democrats to turn out to vote, not to win over undecided voters.
