What can we learn about the 2012 Presidential Candidates from their Facebook presence? Although it’s probably not the most scientific way to predict an election, Facebook can give us some insight into how the candidates are reaching out to fans, and what kind of success they are having in the process.

Social analytics company SocialBakers has come up with a spiffy infographic that looks at the 2012 candidates and how they interact with their Facebook fans, and also looks at what content from their December 2011 postings made the biggest impact.

First off, President Obama is cleaning up when it comes to total fans and total interactions. Obama has nearly 25 million fans on Facebook, and the next closest candidate is Mitt Romney with a little over 1.25 million. Obama also owns 50% of all the social interactions among the 8 candidates, these interactions being described as “all likes and comments from a candidate’s posts plus all likes and comments from people’s posts on the page.”

Although Obama is way ahead in total fans, the fastest mover over the month of December was Rick Santorum. His fan base grew the most of all candidates, nearly 25% last month.

One interesting metric measured in the graphic is the Most Engaging Post, which details the posts from each candidate with the most likes and comments. Obama’s family portrait posted on December 15th swept this category with almost 87,000 likes and 16,000 comments.

Ron Paul’s most engaging post was a Merry Christmas wish while Michele Bachmann’s top post was a new photo album about Iowa added in early December.
