This has been my theory on why in some countries the extreme-right is doing very well (Belgium for example, with Vlaams Belang and NVA). These parties seem to understand that one vote doesn't change much in the grand scheme of things and that the key is to be able to convince a mass amount of voters at the same time. Hence why they are playing the modern media game and spending massive amounts of money into social media campaigns to reach a maximum amount of people. While other parties are not doing that (because they don't realize the game that is being played?) and it shows in election results.

"influencing the votes of other people" should probably be illegal, given the discussion about alledged mass manipulations on U.S. elections.
