President Barack Obama's camp promised that the American public would see a more energized and visionary incumbent on Tuesday night as Obama tries to keep Republican challenger Mitt Romney at bay.
Romney's campaign got a much-needed shot in the arm two weeks ago when the Republican came out swinging in the first matchup between the two candidates, while Obama appeared passive and tongue-tied at times.
The strong debate performance helped Romney reverse his slide in the polls, and recent surveys put the race for the White House at a virtual dead heat just three weeks ahead of the Nov. 6 election.
In a Reuters/Ipsos daily tracking poll on Tuesday, Obama gained a bit more ground on Romney for the third straight day, leading 46 percent to 43 percent.
A Gallup/USA Today poll published on Tuesday showed Romney ahead of Obama by 4 percentage points among likely voters in the 12 battleground states.
Obama aides predicted a stronger showing in the second debate for the president, who hunkered down in Williamsburg, Virginia, for three full days of debate preparation.
"I think you'll see somebody who will be strong, who will be passionate, who will be energetic, who will talk about ... not just the last four years but what the agenda is for the future and how we continue to move ... our economy forward," Obama's senior campaign adviser, Robert Gibbs, said on MSNBC.
The 90-minute debate at Hofstra University in Hempstead, New York, begins at 9 p.m. (0100 GMT Wednesday). Both candidates arrived in New York by midday for final preparation before the debate.
FORMAT COULD BE TRICKY
Obama and Romney will have to deal with the more intimate town-hall format of Tuesday's debate, which often inhibits political attacks as the candidates focus on connecting with the voters asking the questions.
It also offers an element of uncertainty as the candidates cannot predict the questions the audience of undecided voters might pose, which could range from tax policy to job creation to foreign policy.
"Almost all of the pressure will be on Obama this time, given how poorly he performed in the first debate and how much that seemed to help Romney and change the race," said political scientist Andrew Taylor of North Carolina State University.
The town-hall format lets the candidates "talk directly to people and look them in the eye and try to connect, which has not been a strength for either of them," Taylor said. "But you can still make strong points with a velvet glove."
The Reuters/Ipsos poll that gave Obama an edge showed the number of undecided voters had increased, indicating a drop of support for Romney among the coveted voting bloc.
During the first debate, Obama was widely criticized for not challenging Romney on exactly how he plans to give Americans a big tax cut without adding to the deficit, and for not calling attention to the switch to more moderate views Romney appeared to present during the matchup.
For Obama, trying to repair damage from the last debate, the challenge will be to confront Romney on the issues without seeming nasty or too personal.
Romney, a wealthy former private equity executive often accused of failing to connect with ordinary people, would be happy with a steady performance to keep up his momentum.
LINES OF ATTACK
The economy is expected to be a dominant topic. Obama is able to tout the latest jobs report, which showed that the unemployment rate dropped unexpectedly to 7.8 percent in September and reached its lowest level since Obama took office in January 2009.
Romney has countered that the labor market is not healing fast enough.
Glenn Hubbard, one of Romney's top economic advisers, told Reuters on Tuesday the Republican candidate was prepared to question Obama's record on the economy.
"His objective is to continue the conversation with voters about what the right economic policies are for the country," Hubbard said on the sidelines of an economic conference in New York. "He did that really well last time and I'd be stunned if he doesn't do it well tonight."
Romney will likely stay on the offensive over the administration's handling of diplomatic security in Libya before Sept. 11 attacks there that killed the U.S. ambassador and three other Americans. The debate comes a day after Secretary of State Hillary Clinton assumed responsibility for a lack of security that failed to protect against the deadly attack.
Romney may also focus on the Obama administration's subsidies for green energy, after another company - lithium-ion battery maker A123 Systems - filed for bankruptcy protection on Tuesday.
"A123's bankruptcy is yet another failure for the president's disastrous strategy of gambling away billions of taxpayer dollars on a strategy of government-led growth that simply does not work," Romney spokeswoman Andrea Saul said.
For their part, Democrats, hoping to make more inroads with women voters, have hit Romney and his running mate, Paul Ryan, for their opposition to abortion rights.
The Gallup poll highlighted the importance of female voters, who traditionally prefer Obama. The poll showed Romney had pulled within 1 point among likely women voters.
The third and final debate will be next Monday in Boca Raton, Florida, and will focus on foreign policy issues.
