100k in advertising, some of which lasted beyond the election into 2017 verses Clinton’s what, $700 million campaign? That must have really swayed the election, how dare these Russian trolls post memes whilst we pick and choose countries leaders that suit our interests.
You seem to have a poor grasp of what's happened.
You should not compare the figures like for like.
Clintons $700m would be made up of the costs for prime time TV slots, Billboards, Radio Ads, Expensive marketing organisations etc.
The IRA costs identified are just what they paid Facebook for the ad slots.
They do not include how much the Russian State pays to keep the IRA Trolls and its teams of jokers and any other players involved up and running.
And it was a different marketing approach, viral as opposed to mainstream, and very effective it would seem.
The current battleground is Twitter, quite how many accounts are what they seem is debatable, and to an increasing amount, the battleground is smaller social media sites and newpaper and TV comments sections.
It's all about inserting an element uncertainty, an attempt at making people distrust
any news in order to then enable lies and half truths to gain traction in societies amongst the more gullible and those that feel disenfranchised in the modern world.
The Russian State has been doing it to their own people for years, it's just they have now broadened their horizons and all media is a target in this game.
