Obama had another task: Monitoring and managing the federal government's response. At the outset of such catastrophes, presidents have an opportunity to gain support, since they can show they're effectively managing a crisis - though that can backfire, too, as President George W. Bush learned in the bungled aftermath of Hurricane Katrina in 2005.
"This an example yet again of the president having to put his responsibilities as commander-in-chief and leader of the country first while at the same time he pursues his responsibilities as a candidate for re-election," White House spokesman Josh Earnest said Saturday. Obama Saturday spoke to federal emergency management officials on Air Force One by phone.
In Florida, Romney told supporters that they should keep residents along the Eastern Seaboard in "your minds, your hearts." "You know how tough these hurricanes can be," he said.
If the storm intensifies, it's likely to get tougher for Romney and Obama to get the attention of voters in these final, crucial days before the Nov. 6 election. It could also hurt their get-out-the-vote effort in early voting states. Polls show Obama and Romney locked in a statistical tie nationally and in the 11 swing states likely to decide the presidency.
Florida has 29 electoral votes, while New Hampshire has four. If the race remains tight, as expected, even those four votes could be important, and Obama and Romney are neck and neck there.
"These four electoral votes right here could make the difference," Obama told 60 supporters at his first stop Saturday at a Teamsters' hall in Manchester.
Next it was on to the Elm Street Middle School in Nashua, where Obama warned that Romney has "an entirely different view of what this country's about." An audience estimated at 8,500 booed, and Obama smiled and implored them, "Don't boo, don't."
He joked about Romney's 2003-2007 stint as governor of Massachusetts, a state just minutes away from the campaign site. "He raised fees to get a birth certificate," Obama joked, "which would have been expensive for me." Obama was born in Hawaii, and released his long-form birth certificate last year, but some critics have questioned his place of birth.
He also continued to make a special appeal to women, insisting, "We don't need a whole bunch of politicians in Washington, most of whom are male, making health-care decisions for women."
Romney made his case in Florida, which narrowly voted for Obama in 2008. Polls this week show Romney inching ahead there as the economic downturn has hit the state particularly hard, leaving a slew of home foreclosures and an unemployment rate higher than the national average.
He spoke at the civic center in Pensacola, a Panhandle city with strong ties to the military. Lines to get in stretched around the block. Romney spoke on a stage in front of a massive American flag and a massive blue sign promising "Real Recovery."
Romney criticized Obama for failing to get people back to work, pushing the new health-care law and for waging a campaign of petty attacks.
"Four years ago Obama spoke about big things and now he is reduced to talking about small things," said Romney, who for days has tried to appear presidential by sticking to broad themes without many specifics.
He talked about how Republicans would work with Democrats, as he did when he was governor of Massachusetts.
Romney also answered an Obama attack from Monday's presidential debate, when the president ridiculed Romney's complaint that the Navy has fewer ships than at any time since 1917 by saying the U.S. military also has "fewer horses and bayonets, because the nature of our military has changed."
"In fact, we do use bayonets," Romney said to cheers.
Crowds for both candidates arrived hours early and cheered enthusiastically. "How often do you get a chance to see the next president?" said James Peterson, who attended the Romney rally with his 10-year-old, Trevor. The two arrived at 8 a.m. for the noontime rally.
In Nashua, Obama supporters showed just as much passion for their candidate. Natalie Audette, a health insurance saleswoman, praised the administration's support for health-care programs. Her two children both need aid, and a Romney administration, she said, would leave such decisions up to states. Obama adds emphasis to the campaign!
President Barack Obama's campaign added an exclamation point to placards and banners bearing the campaign's motto.
Instead of a stoic period at the end of the single-word slogan, the signs now read "Forward!" The president's team added the exclamation point earlier this week, just in time for Obama to kick off a marathon, 40-hour battleground-state blitz.
Obama spokeswoman Jennifer Psaki said the campaign pumped up the slogan to reflect "the stakes in this election and energy at our events."
