Obama and Romney square up for 2nd TV debate Barack Obama's campaign managers are promising their man will rebound against Mitt Romney in tonight's second TV presidential debate. Romney was generally thought to have won the first encounter. Since then his support in the polls and his personal approval ratings have been on the rise. Three weeks to the day before America decides who will go to the White House, the two candidates are to face questions from members of the public in what they call a "town hall" format. Romney's advisers have suggested he will continue to moderate the tone of his conservative message to help attract undecided voters. With both men nip-and-tuck in the polls, Obama's campaign promised a more energetic president than appeared last time.
