But in the first fundraising quarter since Brown announced his bid, his haul has been matched — if not eclipsed — by Shaheen's.
From April through June, Shaheen brought in more than $2.8 million, her campaign announced Monday, bringing her total contributions to more than $10 million for the election cycle. Shaheen finished last month with more than $5.1 million on hand.
Brown's campaign downplayed Shaheen's fundraising for the quarter. “It’s clear that both campaigns are going to have the resources they need to get their messages out. That won’t be a problem for anyone in this election," said Elizabeth Guyton, a spokeswoman for Brown's campaign. "Sen. Shaheen’s problem is her message."
Brown's campaign has not released a final fundraising total for the quarter, but estimates the haul at "north of $2 million."
That would mean Brown's fundraising performance is vastly diminished from 2012 -- when, during the same quarter in his bid for re-election in Massachusetts against Elizabeth Warren, he raised nearly $5 million.
The two fundraising tallies are not perfectly analogous, however. In 2012, Brown and Warren agreed to disavow outside spending, meaning all money would be raised and spent directly through their campaigns. And the race, seen as a prime pick-up opportunity for Democrats, drew attention from donors of both parties nationwide. During the same period that Brown raised $5 million, Warren brought in an eye-popping $8.6 million.
For both Shaheen and Brown, Massachusetts connections have left a mark on fundraising thus far. Mitt Romney, a former governor of Massachusetts, has endorsed Brown and headlined an event for his campaign; meanwhile, Warren has worked to raise money for Shaheen.
Shaheen also received a big-name boost from former President Bill Clinton, who headlined a New York fundraiser for Shaheen on June 16.
Outside groups, too, have had an outsized role in the spending race. The biggest player on the Republican side, Americans for Prosperity, has spent roughly $1.2 million against Shaheen, a local spokesman told the New Hampshire Journal; meanwhile, Democrats have countered with nearly $700,000 attacking Scott Brown via the Senate Majority PAC, according to the group Open Secrets, which tracks campaign spending.
That level of outside spending has yet to boost Brown in the numbers game that ultimately matters most: the polls. In recent public surveys Brown has consistently trailed Shaheen by low double-digits.
