With just a few days left, it seem increasingly unlikely that there's going to be an "October Surprise" -- or something that might change this election's trajectory.  In 2000, it was President Bush's DUI arrest; in 2004, it was Osama bin Laden's statement. As CNN reports:

It's Halloween on Friday, but campaign aides to Barack Obama and John McCain may be spooked for another reason: Events that dominated the news right before the previous two presidential elections may have been game-changers.

Aides to Sen. John Kerry were increasingly confident of victory four days before the 2004 election, believing the Massachusetts senator performed strongly in three debates with President Bush and was buoyed by polls showing a last-minute surge for the Democratic ticket.

But that was before Osama bin Laden weighed in...

On the Friday before the 2000 election, Americans woke up to another headline that dominated the dwindling days: The night before, Bush acknowledged he had been arrested for driving under the influence in 1976 in Maine.

So, is it too late for an October Surprise?
