A political meme is a purposefully designed visual framing of a position. Memes are a new brand and fashion of political messages, campaigns, and advertising. It is a new way of communication ... a joke or humor understood only by a particular group of people. They are inside jokes or private jokes and has the ability to trigger an emotional reaction.
Memes work politically if they go viral when shared on any social media platform ... and if they help foster and nurture affinity, attachment, and a sense of belonging to a political party, circle or “in-group” and if they make a strong and riveting statement about a public figure or political issue.
Memes can spread rapidly online and into popular culture due to their shareability — they are easily created, consumed, altered, and disseminated. They can quickly communicate the creator’s stance on the subject. The stronger the emotional response provoked by a post, the greater the intent to spread it.
