Romney Campaign Reassesses Itself After Super Tuesday Aides are hoping to strengthen Mitt Romney's ability to connect with voters and put out a sound-bite-friendly economic plan. BOSTON - Mitt Romney sought to reassure contributors, supporters and party leaders on Wednesday that his bid for the Republican presidential nomination remained on track, convening a daylong strategy session at his campaign headquarters here to recalibrate and elevate his candidacy above the tedium of fighting for delegates. Mr. Romney, aides say, has become too mired in the nuts and bolts of how to win the nomination rather than offering an inspiring argument for why he should. Trying to gain the upper hand and assert himself as the likely nominee, he is set to focus on his economic plan, spend more time with American workers and try to unite Republicans around defeating President Obama. A day after the Super Tuesday contests added six more states to his winning record, including a narrow Ohio victory that spared him an even tougher round of second-guessing, Mr. Romney huddled with his advisers to address the deficiencies that have become clear during two months of rigorous campaigning. There were no immediate recriminations, aides said, but widespread agreement that he and his campaign must improve their performance. "We're in a new phase of the campaign," said Matt Rhoades, the campaign manager. We'll start to more aggressively highlight Governor Romney's plan to turn around the economy. We'll use speeches and more media hits to drive the jobs message against President Obama and his failures. While Mr. Romney had hoped that a strong enough finish on Super Tuesday could persuade his Republican rivals to reconsider their candidacies, his aides acknowledged that the competition with Rick Santorum and Newt Gingrich could now last until June. His campaign held a briefing here on Wednesday, where advisers argued that Mr. Romney's lead in the delegate count has become nearly insurmountable, even if his opponents would not acknowledge that. The aggressive posture comes as the Romney campaign braces for a challenging stretch of primaries and caucuses in the South and Midwest over the next two weeks, where voters in Kansas, Alabama, Mississippi and Missouri will make their presidential preferences known. Aides were trying to pre-empt a narrative from hardening that Mr. Romney was struggling to connect with working-class and lower-income voters. But as Mr. Romney has lurched from contest to contest - sometimes winning, sometimes losing - his supporters in the party have become increasingly agitated at his inability to move beyond a slate of competitors who are not known as huge political talents with well-financed or well-organized campaigns. "I think Romney's supporters would be eager to put away what is perceived as an underfunded, second-tier field sooner than they've been able to," said Mike DuHaime, a senior political adviser to Gov. Chris Christie of New Jersey, a top Romney supporter, and a veteran of the presidential campaigns of John McCain, Rudolph W. Giuliani and George W. Bush. But that doesn't change the fact that Governor Romney is going to be the nominee. He said, however, that the performance of Mr. Santorum, a former senator, on Tuesday left little room to pressure him to withdraw so Republicans could focus on Mr. Obama. "I don't think it's credible to ask Senator Santorum to drop out at this point," Mr. DuHaime said, "even if it's hard to see a path." The Romney campaign headquarters here in the North End of Boston was bustling with activity on Wednesday, as Mr. Romney made only his second visit of the year. He spent several hours meeting with close advisers, who presented a plan forward for his candidacy. "I'm prepared to fight all the way to become the nominee," Mr. Romney said in a television interview on CNBC's "Squawk Box" program, his only public appearance of the day.
