President Bush and Democratic challenger Senator John Kerry are concentrating on winning over undecided voters as they head into Wednesday's third and final nationally-televised debate.
The face-off between the two candidates Wednesday in Tempe, Arizona will focus on domestic issues, such as the economy, health care, taxes, education and energy costs.
Mr. Bush and Mr. Kerry each stepped up their verbal attacks on each other Monday, sharply criticizing the other's stand on the war in Iraq and how to best fight terrorism.
Both candidates are focusing their efforts on targeting undecided voters in so-called "swing states" whose support could make or break the race for either man.
The latest polls indicate Mr. Bush and Mr. Kerry are in a virtual tie. The election is November 2.
