McCain and Obama face off over economy in 3rd presidential debate

Republican John McCain, battling to reverse his slide in the polls in a high-stakes debate, said Wednesday that preventing home mortgage foreclosures was the key to "putting a floor under" the US economic crisis and attacked Democrat Barack Obama for planning to raise taxes. In their third and final presidential debate, Obama countered, as he has throughout the campaign, that he would cut taxes for 95 percent of earners while raising it on the richest Americans, those making more than $250,000 a year.
