Word had only leaked that David Axelrod, a arch strategist for President Obama’s campaign, would arrive a subsequent morning to conflict Mr. Romney on a stairs of a State House, a half-mile away. The debate detonate into full heckling mode — producing “Go Back to Chicago!” signs, rounding adult a burble appurtenance and anticipating a spacesuit dress (“Astronomical debt!”). 

“If ever there was a unresolved bend ball, it was a thought of perplexing to lift off an Obama eventuality within a brief travel from a Romney headquarters,” pronounced Stuart Stevens, a arch strategist for a Romney campaign.

Drowning out Mr. Axelrod’s news discussion with shrill boos — a tactic that could be seen as vulgar — seemed to vigilance a kind of conflict Mr. Romney’s group intends to salary over a subsequent 5 months: one that takes no push easily and provides no easy opportunities for Mr. Obama to make his case.

Mr. Romney is already using a debate he and tip aides contend they envisioned some-more than a year ago — forcing Mr. Obama to urge his mercantile record in a murky environment.

Now, Mr. Romney skeleton to double down on a campaign’s plan of perplexing to keep a boss on a defensive by refusing to let a concentration wandering from a struggles of normal Americans, a thesis that can ring no matter a short-term arena of a economy. That charge might be easier in a arise of Friday’s diseased jobs report, that supposing uninformed justification that a mercantile liberation was slowing.

“This will be a prolonged debate filled with ups and downs,” Matt Rhoades, a debate manager, wrote in an e-mail. “We know we are going adult opposite an obligatory boss who is good financed and has an gifted group operative for him.  But Governor Romney has a improved summary and knowledge traffic with jobs and a economy.”

Mr. Romney had his ungainly moments in May.

Even as he clinched a assignment final week, he spent a day fortifying his preference to reason a imagination Las Vegas fund-raiser with Donald Trump notwithstanding a genuine estate mogul’s lifting doubts about a flawlessness of Mr. Obama’s birth certificate. The president’s attacks on Mr. Romney’s knowledge during Bain Capital also generated headlines. And a Washington Post article about a bullying part during Mr. Romney’s high propagandize days knocked a claimant off message. 

No one in a Romney debate is doing a feat dance. Veterans of past presidential campaigns know unequivocally good that conjunction group has nonetheless to entirely rivet a billion-dollar debate machines that will strife in fantastic conform in a fall.

But a clarity of confidence in Boston is palpable. Mr. Romney’s aides contend a Obama debate has been reduction trained than they expected, relocating from one line of conflict to another in May. By contrast, Mr. Romney has expelled a array of radio ads that aim to answer a question: What would a Romney presidency be like?

Mr. Romney’s advisers trust a president’s efforts to conflict their candidate’s business knowledge have been undermined by a array of Democratic defections from a authorized celebration line. On Thursday, former President Bill Clinton became a latest Obama broker to go off message, proclaiming Mr. Romney’s business record to be “sterling.”

“Their possess guys are out there saying, actually, Romney has a unequivocally good record. Why would we do anything to get in a way?” pronounced Sean Spicer, a Republican National Committee’s communications director.

The formula of new polling in pitch states have been mixed. Mr. Obama binds advantages in Ohio, Wisconsin and Pennsylvania. But other surveys advise that Mr. Romney has begun to tighten in on a boss after a sour and divisive nominating deteriorate in that Mr. Obama was clearly forward in inhabitant polls. The many new Gallup tracking poll has them radically tied; some polls in bridgehead states like Florida and Virginia put a competition unequivocally close.

The past week, aides said, highlighted a strengths of a Romney operation: discipline, potency and execution. In further to fast mobilizing to interrupt Mr. Axelrod’s news conference, a debate also managed to keep a warn revisit by Mr. Romney to a domicile of Solyndra — a unsuccessful solar-panel association that perceived millions of taxpayer dollars — tip until mins before a eventuality in Fremont, Calif. (It was small noticed, however, occurring as former President George W. Bush was during a White House for a phenomenon of his central portrait.)

Advisers to a Romney debate pronounced that after a bruising nominating contest, a group was fervent to go on a offensive. It has increasing a numbers so that overburdened aides doing a jobs of 3 or 4 people can now concentration on their specific tasks.

On Friday, surrogates for a debate descended on Boston for dual days of meetings and training on how to best get out Mr. Romney’s message.
