This may be Republican presidential candidate John McCain's best, and possibly his final, chance to turn his campaign around. Democrat Barack Obama is leading McCain between 2 and 10 percentage points in most tracking polls.
But McCain has been there before. Look for McCain to go on the offensive, and perhaps try to link Obama to the liberal group ACORN, whom Republican officials and conservative broadcasters accuse of voter registration fraud in key states.
Overnight, Obama's campaign conceded that he had done legal work for the group in the past, and donated funds to help their registration drives. Look for Obama to again attack McCain's health care plan, and perhaps McCain's interest in privatizing Social Security. The debate starts at 9 tonight. The chat begins shortly after 8 pm.
