Get ready for this year's "October Surprise" - the news event in the weeks before the presidential election that has the potential to push the remaining undecided voters behind one candidate and decide the outcome.

Here's a sneak peek at the "surprise."

In late October, President Obama announces his campaign is tapped out of money and unable to answer the final round of attack ads from his opponent, Mitt Romney. 

This scenario is no longer outside the realm of possibility. 

On a recent conference call with potential donors, President Obama said: "If things continue as they have so far, I'll be the first sitting president in modern history to be outspent in his reelection campaign."

The president then asked his donors "to meet or exceed what you did in 2008." 

That is a pretty high bar to clear. 

In 2008, Obama shattered all campaign fundraising records by bringing in more than $700 million. His GOP opponent, John McCain, raised only $316 million, giving the Democrat a tremendous advantage.
