WASHINGTON (CNN) - The third and final presidential debate is shaping up to be a make-or-break appearance for both Sens. John McCain and Barack Obama, one of the last chances to get their message out to undecided voters.
The debate, taking place at Hofstra University in Hempstead, New York, begins at 9 p.m. ET Wednesday and will be aired live on CNN and CNN.com.
The 90-minute face-off will undoubtedly focus on the economic crisis plaguing the country. And unlike at the other two debates, the candidates will sit at a table facing one another.
CBS News' Bob Schieffer, host of "Face the Nation," will moderate the debate and told The Associated Press on Sunday that he will be seeking more on what each will bring to the presidency.
