Sen. Jeanne ShaheenCynthia (Jeanne) Jeanne ShaheenAmerica will not forget about Pastor Andrew Brunson Shaheen sidelined after skin surgery Members of Congress demand new federal gender pay audit MORE (D-N.H.) raised $1.1 million in the last three months of 2013 and now has $3.4 million cash in the bank for her reelection fight, her campaign announced Thursday.

Her campaign is touting the fact that 95 percent of the contributions the senator received came in sums of less than $250, typically an indicator of strong grassroots support.

Shaheen raised $4.5 million overall in 2013.

"The support our campaign has generated to date shows that we'll have the resources we'll need to run an aggressive, winning campaign this year regardless of whom Republicans nominate to run against Senator Shaheen," said Andy Darkins, Shaheen’s finance director.

Four Republicans have already jumped into the race, including former New Hampshire Sen. Bob Smith, but Shaheen’s greatest potential threat remains in former Massachusetts Sen. Scott Brown (R), who is considering a bid but has yet to make a decision on the race.

Brown is considered formidable because of his strong fundraising and campaigning abilities and national profile, and while he’s taken steps toward a run in the state — including moving to the state from Massachusetts — many of his actions have left Granite State political operatives scratching their heads.

A Democratic poll out Wednesday showed Brown trailing Shaheen by just three points, the best showing of all the Republican contenders in the race.

But Democrats argue the poll showed no significant change from another survey, conducted in September, showing Brown behind by four points — and in the interim, Shaheen has been the target of hundreds of thousands of dollars in attacks from outside GOP groups focused on ObamaCare.
