CNBC’s Ego Trip: Obama, Romney, Google or Armstrong?

CNBC’s Ego Trip: Obama, Romney, Google or Armstrong?

In a world where self-esteem can be more volatile than the markets, we want to know which ego in the financial and political world took the biggest ride, good or bad, each Friday.

This week's winner, with 31.5 percent of the vote, is President Barack Obama.

The president went on the offense when he faced Republican candidate Mitt Romney Tuesday night during the second presidential debate at Long Island's Hofstra University.

Under heavy pressure for a comeback, Obama accused Romney of favoring a "one-point plan" to help the rich at the expense of the middle class. The open-stage and town hall format allowed the two candidates to stroll freely across the red-carpeted area, and they did. (Read More: Obama Regains His Footing in Feisty Second Debate.)

Romney took second place in our weekly poll, with 29.5 percent of CNBC's social media fans saying they felt the Massachusetts governor held his own in the debate.

In third place was Google, along with its CEO Larry Page, with 21.5 percent of the votes. The company's earnings were mistakenly reported early on Thursday, causing the stock to plunge. The news immediately went viral on Twitter.

To make matters worse, the top of the early report had "Pending Larry Quote" plastered across it. The Internet giant blamed the error on its printer and communications consultant RR Donnelley. (Read More: 'Pending Larry' From Google's Earnings Release Goes Viral.)

Last but not least, Lance Armstrong's ego received 17.5 percent of the responses. After Nike, Armstrong's principal corporate sponsor for many years, announced that it was breaking off all ties with Armstrong because of a doping scandal, other companies followed suit. Facebook fan Taiwo Idowu, who voted for the now-infamous cyclist, commented, "What a fall!" (Read More: Armstrong Loses Eight Sponsors in a Day.)
