(CNN) - The New Hampshire Republican Party is going up with a new web video that links Democratic Sen. Jeanne Shaheen to President Barack Obama and to the federal health care law.
The Monday release of the video comes on the same day that Shaheen's campaign went up with a radio ad critical of former Sen. Scott Brown of neighboring Massachusetts, who's now taken a key step towards challenging Shaheen.

The video by the New Hampshire GOP questions whether Shaheen, who's up for re-election this year, will ask the President to campaign with her. It uses a clip of the senator saying "we don't know if he'll come here or not," after being asked if she would like Obama to join her in the Granite State. And it also claims that "Shaheen votes with Obama 99 percent of the time."
Last week, in an interview with New England Cable News, the President praised Shaheen, who could face a tough race this year if Brown formally jumps into the New Hampshire race and wins the GOP Senate nomination. Brown, who moved north to the Granite State last year, recently announced an exploratory committee, an important step towards launching a bid.
The New Hampshire GOP's release of the video comes one day before Vice President Joe Biden visits the state, for an event on workforce development and job training. The Vice President will be joined by Secretary of Labor Thomas Perez at NH Works, an on-the-job training program that works with 170 businesses statewide.
A Shaheen aide tells CNN that some votes on Ukraine and a hearing of the appropriations subcommittee, which she chairs, will keep the senator in Washington Tuesday as the Vice President heads to New Hampshire.
Republicans are trying to tie Shaheen to Obama.
"With Vice President Biden in town tomorrow, I'm looking forward to Senator Shaheen explaining to the people of New Hampshire she has voted for the Obama-Biden agenda 99 percent of the time, and invite her to bring both Biden and President Obama back many, many more times between now and November," said NH GOP chair Jennifer Horn, in a statement.
Then-Sen. Obama won New Hampshire, which is considered a battleground state, by nine percentage points in his 2008 presidential election, and carried the state by six points in his 2012 re-election. The President made five campaign stops in the Granite State during the 2012 election cycle, according to an unofficial count by CNN. But the President's current approval rating in the state stood at 40% in a recent Suffolk University/Boston Herald poll and at 31% in an American Research Group survey.
If Brown ends up winning the party's September primary, it could expand the map for Republicans. Democrats hold a 55-45 majority in the Senate (53 Democrats and two independents who caucus with the party), but are defending 21 of the 36 seats up in November, with half of those Democratic-held seats in red or purple states, like New Hampshire.
But the Suffolk University and ARG polls indicate Shaheen has a double digit lead over Brown in a general election showdown. According to the ARG survey, 50% of Granite State registered voters say they would support Shaheen, with 38% backing Brown and 12% undecided. And Shaheen had a 52%-39% lead among New Hampshire voters in the Suffolk University poll.
New Shaheen radio ad spotlights pledge
As the state GOP was putting out their video, Shaheen's campaign was launching a radio ad that attacks Brown for not signing a pledge to keep outside money out of the Senate race.
"Scott Brown's changed more than his address," says the announcer in the spot, which then uses a clip of then-Sen. Brown of Massachusetts touting a pledge he signed with Democratic challenger Elizabeth Warren in his 2012 campaign. Brown ended up losing his bid for re-election in the Bay State.
Democrats are now criticizing Brown for refusing to sign a similar pledge.
"Not long ago, Scott Brown said he was 'really disgusted' with SuperPAC ads. Now Scott Brown won't sign his own pledge to stop them. Maybe it's because Big Oil and Wall Street want to buy him a Senate seat."
A Democratic source with knowledge of the radio commercial describes the ad buy as significant.
Brown quickly reacted to the new Shaheen spot, saying "It's disappointing that Senator Shaheen's first ad of the campaign is a negative ad attacking me."
Brown won't sign the new pledge, saying it comes too late because outside groups have already spent big bucks on the race.
