Last Call for Game-Changers

In the depths of an economic crisis, recent polls show that attacks are backfiring on John McCain. But the message from his Republican base was to come out swinging. That he did in last night's debate—on taxes, healthcare and Barack Obama's alleged association with 60's anti-war extremist Bill Ayers. In what's being called the "most intense," "spirited and combative" of their three debates, Obama maintained what one paper labeled "amused detachment." With so little time left, did it make a difference? Did McCain successfully separate himself from President Bush? Did Obama stay ahead by staying cool? What about the economy? We hear from strategists on both sides and get reaction from the battleground states of Virginia, Ohio and Indiana.
