Over the past days, despite appearing unwell in public, neither Hillary Clinton or her press office were able to confirm that she was suffering from pneumonia – that was until she fainted publically at a 9/11 memorial service.

Due to this lack of communication, social media speculation filled the void. The price of not speaking openly to the digital crowds was the emergence of the memes like this:

We’ve all seen memes of this ilk before. A political event happens and Twitter and Facebook timelines are filled with crude graphics and snappy jokes.

Memes play the role of “fast-food media”. People use them to upgrade the visibility of the news, advance ideas and viewpoints, and suggest their own (often alternative) interpretation. Armed with a quick and sharp commentary, an internet meme has the power to go viral in the chaotic space of social media communication. Social media users do not have to spend time reading a lengthy opinion piece or browsing blog posts, they notice memes within seconds from the corner of their eyes, click “like”, “share”, “retweet”.

In the over-saturated information space, where people are exposed to the myriads of media, social media, advertising and marketing messages, memes become easily consumable and enjoyable vehicles of information and opinion. For political communication, one viral meme can say more about public opinion than a dozen surveys. And at the same time, memes can form the agenda and influence the judgements of the audience.

The most memorable perhaps is the unfortunate bacon butty breakfast of Ed Milliband a few years ago. The internet turned the unflattering photo in a viral hit, ridiculing the politician’s attempts to appeal to Labour voters.

Internet memes cannot explain complex issues to the public, yet they have the potential to reach large audiences at a time when traditional media consumption is in decline. An invaluable tool for any politician.
