U.S. Sen. Jeanne Shaheen insisted yesterday she doesn’t plan to follow the Elizabeth Warren playbook for beating Scott Brown, but experts say she took a page from it in the fledgling Granite State Senate fight, slamming the Republican prospect as a corporate “apologist” — echoing some of Warren’s favorite attacks.

Shaheen told reporters after a University of New Hampshire Law School event yesterday that she’s not yet thinking of whether she’ll bring Warren, the party’s progressive darling, on the campaign trail with her, and indicated she’ll chart her own course apart from tactics the Massachusetts Democrat used in her 2012 Senate victory over Brown.

“I think New Hampshire is different than Massachusetts,” Shaheen said. “We’re the live-free-or-die state. We are independent, we have different issues that have been important here. I intend to talk about what’s important to New Hampshire.”

But when asked what are the biggest differences between her and Brown, who announced last week he’s exploring a run against New Hampshire’s senior senator, Shaheen went straight to Warren’s tried-and-true Brown jabs.

“What we saw in his time in Washington is that he was an apologist for Wall Street. … He was an apologist for the oil and gas industry,” Shaheen said, adding that Brown took “hundreds of thousands of dollars” in campaign donations from those popular Democratic whipping boys.

UNH political science professor Dante Scala said it’s part of an expected Shaheen strategy: to “meld” Warren’s winning hits with her own attacks on Brown as a carpetbagger.

“I don’t think anybody is going to mistake her for Elizabeth Warren,” Scala said. “Her biggest worry is to energize the Democratic base in New Hampshire. This was a huge problem four years ago. Republicans turned out, Democrats did not.”

A solution to that could be bringing in Warren to rally donors and activists, experts say. Warren, for her part, sent out an email last week after Brown made his intentions official, urging her supporters to get behind Shaheen.

Harvard professor Marty Linsky said, “In some ways, the more she takes from the Warren playbook the better it is for Brown because his strategy is to push her as far to the left as possible.”

But expect Shaheen’s hits to keep coming.

“She’s historically run very negative, hard-hitting campaigns,” said Andy Smith of the UNH Survey Center.

“She will use whatever she thinks is best from Elizabeth Warren’s campaign and use those attacks on Brown here.”
