Propaganda, but they hit all the effective points being used against them: Fri 4 Nov 2016 10.00 GMT; "Meme warfare: how the power of mass replication has poisoned the US election": https://www.theguardian.com/us-news/2016/nov/04/political-memes-2016-election-hillary-clinton-donald-trump

Memes – from the Greek for “that which is imitated” – were once defined as being self-replicating units of culture. This included anything that could be learned, remembered and spread from one brain to another, such as the concept of god all the way to the popular Budweiser “Wazzup” catchphrase.

Through the internet, the idea moved from the conceptual sphere into the viscous reality of data and pixels, transforming it into something more traceable: a segment of media that is copied rapidly. This includes images, text, video, a combination of all three and sometimes real-world actions.
