Will Warren’s visit spell déjà vu for Brown?

Sen. Elizabeth Warren (D-Mass.) may have defeated Scott Brown two years ago, but she is still haunting him even as the former Massachusetts Republican takes his campaign to New Hampshire.

Warren is in New Hampshire this weekend campaigning for Brown’s opponent, Sen. Jeanne Shaheen, a first-term senator and former governor of the state who is locked in a close race with Brown.

Shaheen hopes Warren’s presence will spell déjà vu for Brown. The two New England Democrats are making campaign stops Saturday in the New Hampshire towns of Durham, Concord, Keene, in advance of the Nov. 4 election.

It’s a busy weekend for Warren.

On Friday, she also appeared with Hillary Clinton at a campaign event for Martha Coakley, a Democrat running for governor in Massachusetts.
