Conversation Starters: Gingrich on Military Service, Paul on Newsletters, and Romney on Bain Jobs

After a half hour of debating, the topics getting the most attention among viewers who are talking about them online are Newt Gingrich avoiding military service, Ron Paul explaining controversial newsletters that mentioned race, and Mitt Romney defending his claim that he created 100,000 jobs while at Bain Capital.

That's according to the analysts at BlueFin Labs, who are tracking the conversation of the ABC News debate on Twitter on this Saturday night.

Some details from their report: Paul's critique of Gingrich not serving served in the military was the most "dominant" moment of the debate's early portion, at least on social media. That exchange prompted 5,900 messages on Twitter.
