(CNN) - Add another organization to the list of outside groups running ads in the Senate battle in New Hampshire, which is turning into a key race that could determine which party controls the chamber next year.
CNN has learned that Independent Leadership for New Hampshire is going up Tuesday with its first television commercial in support of Republican Senate candidate Scott Brown.

The Super PAC was formed a couple of months ago to support Brown, the former GOP senator from neighboring Massachusetts who moved to the Granite State late last year and is considered the heavy favorite to win next month's Republican Senate primary. The release of their first ad comes just a few days after a new poll indicated Brown was basically all tied in a November general election showdown against Democratic Sen. Jeanne Shaheen, the state's former governor.
The spot features Jennifer Nunez, a voter from Gilford, New Hampshire.
"I'm a single mom. It seems like gas prices are always going up, oil prices are going up, my groceries are going up, electricity's going up. I'm doing the best that I can to make ends meet," says Nunez in the ad.
Nunez, who's currently a registered Republican, adds that "I voted for Jeanne Shaheen as governor but I would not vote for her again. I don't feel like Jeanne Shaheen is helping people like me. How do you vote with Barack Obama 99% of the time and still say you're an independent? I feel like Jeanne Shaheen has changed and the middle class has paid the price."
Independent Leadership for New Hampshire, which is run by Granite State based GOP strategist Patrick Hynes, tells CNN that it will spend six figures to run the ad statewide on broadcast TV.
While commercials from outside groups focusing on the Senate race have flooded Granite State airwaves, an official with Independent Leadership for New Hampshire says their spots may stand out because "we've got real people from New Hampshire, predominantly women, talking about how the polices of Sen. Shaheen and President Obama are negatively impacting their lives."
The Shaheen campaign, in a statement, said that "Scott Brown has a history of making personal attacks to score political points. Now Scott Brown and his allies are attacking Jeanne Shaheen for her advocacy for breast cancer research and for health care for women fighting breast cancer."
"Scott Brown ought to be ashamed of his buddies twisting the facts and misleading New Hampshire," added Shaheen campaign spokesman Harrell Kirstein.
The spot was one of three ads to come out on Tuesday that backed Brown. The Ending Spending Action Fund, a conservative outside group that's been very critical of the new health care law, said it was spending seven-figures to go up with what it called a multidimensional effort attacking Shaheen that includes a minute long spot that accuses the Democratic senator of cronyism.
"The Shaheen family gets richer. New Hampshire families get the bill. Washington has changed Jeanne Shaheen," says the narrator in the ad.
The group went up with commercials last December advocating a draft Brown movement, in the months before Brown announced his candidacy.
"We’ve all seen some pretty low, really irresponsible, completely made-up political attacks over the years, but Ending Spending is sinking to a new low, bringing Massachusetts style politics here to the Granite State. Their ad is outrageous and false," said Shaheen campaign manager Mike Vlacich, in a statement.
Meanwhile, the Brown campaign Tuesday released a new ad in which the state's other senator, Republican Kelly Ayotte, says "I support Scott Brown because I know that he's for fiscal responsibility, accountable government, and finally a health care plan that works for all of us. He will give everything he's got for New Hampshire."
The Independent Leadership for New Hampshire PAC's spot follows the Republican strategy of trying to tie Shaheen to the President. A WMUR/Granite State poll released last week indicated that Obama's approval rating in the purple state is down to 38%. The President grabbed 52% of the vote in the state in the 2012 election.
That same survey indicated Shaheen with a slight two-percentage point margin over Brown in a general election showdown, which is within the poll's sampling error. Surveys earlier this summer showed Shaheen with leads between 8 and 12 points.
Before Brown can concentrate 100% on Shaheen, he first has to deal with the September 9 GOP Senate primary. Brown is considered the overwhelming favorite in that contest against former U.S. Sen. Bob Smith and former state Sen. Jim Rubens.
If the GOP can flip the seat in New Hampshire and five others, without losing any ground, they will win control of the Senate in November's elections.
Democrats have a 55-45 majority in the Senate (53 Democrats and two independents who caucus with the party). But in the midterms, the party is defending 21 of the 36 seats up for grabs, with half of those Democratic-held seats in red or purple states like New Hampshire.
