Both candidates are preparing for the critical debate, set for Tuesday in Hofstra University in New York.
The debate will be a town-hall style event and voters will have a chance to ask questions as well as the moderator, Candy Crowley of CNN.
The presidential candidates will debate both local and foreign policies.
Obama is likely to pitch his economic vision, which focuses on a tax breaks for the middle class and tax increases for the wealthy and criticize Romney for favoring rich people. Romney is expected to reiterate his criticism on Obama's finance policies,and lie heavily on Obama on the Benghazi attack killing American ambassador to Libya.
Obama is expected to be more aggressive in responding to Romney and stage a stronger performance by being more enthusiastic instead of being "academic".
The debate will give Obama a chance to mend the damage of the first debate while give Romney an opportunity to maintain his passionate attitude in order to persuade more and more indecisive voters.
Eyes were on Romney at the first debate since Obama was favoured for that, but quite the opposite is valid for the second one. Experts say that if Romney wins the second debate that would cost Obama losing the elections, but the format of the debate would help Obama since he is more comfortable when addressing live audiences.
As a tradition during elections campaign period, Obama and Romney will be facing off against each other on October 22, for the third time, two weeks before the Election Day, in Florida to debate only foreign policies.
Such debates have become a tradition in U.S. politics for almost the past five decades and most of the time, U.S. television programs play a big role on presidential election results.
Meanwhile major surveys show that Romney had closed the gap or overtaken Obama in the past two weeks on a range of issues.
