During presidential campaign season, it’s critical for candidates to get in front of as many eyes as possible. Importantly, it helps to get a lot of time in front of those eyes.

But campaigning isn't cheap.

Fortunately, social media offers free platforms, where articles and Tweets about candidates can get passed around like crazy. And according to data and analysis from SocialFlow, when it comes to having a big presence on social media, one candidate is king: Donald Trump.

During March, SocialFlow estimates that people have spent around 1.94 million hours reading Trump content that was shared on Twitter (TWTR), Facebook (FB), and LinkedIn (LNKD). This compares to around 630 thousand hours spent reading content about Hillary Clinton.

“Donald Trump has demonstrated a showman’s ability to dominate the conversation," SocialFlow CEO Jim Anderson said to Yahoo Finance. "On social media he’s been able to generate billions of impressions, which translate into millions of hours of exposure."

And yes, there is indeed real value that can be attached to all of those hours. SocialFlow estimated.

"The value over the course of a year is about $383 million," Anderson said of Trump's visibility.

"By comparison, Hillary Clinton, who does quite well with social media herself, is getting about $90 million worth of free exposure on social media," Anderson added.

A year ago, however, those positions were reversed. According to SocialFlow, people spent around 64 thousand hours reading content about Clinton versus just 3,500 hours reading content about Trump.

Now, it’s unclear how much of this is negative versus positive content for each of the candidates. But if you subscribe to the rule “There’s no such thing as bad publicity,” then Donald Trump is getting the richest free publicity ride.

"This is the first Presidential election where success or failure in social media could very well decide the election," Anderson said.
