Debate stakes higher for McCain

WASHINGTON  - It could be quite a presidential debate

Tuesday night.

John McCain is running short on time, and has the most riding on

the outcome. He prefers town hall-style confrontation.

The debate comes exactly four weeks before Election Day and

polling suggests Obama is approaching the 270 Electoral College

votes needed for victory.

The target audience is the roughly 10 percent of the electorate

who are undecided and an additional quarter who say they might

still change their minds before November 4th.

In the 90-minute debate at Belmont University in Nashville,

Tennessee, NBC newsman Tom Brokaw will facilitate questions from

the audience.

The debate is supposed to be divided equally between the economy

and foreign policy, but given the global financial turmoil,

economic questions may well dominate.
