And we all know an inevitable end result of this. Ready?
A major party candidate is running for a high office. A video surfaces showing said candidate in sexual congress with an underage female, perhaps purporting to be from a security camera in a Thai whorehouse. It's a good enough fake that it's impossible to shake, and the partisans latch onto it like barnacles, posting and reposting it ad nauseum. The candidate loses his campaign, gets hauled up on charges and spends time in prison where he is killed, all for a faked video. A year of two later the video is proven fake, but the damage is done, and no one can track down the originator for prosecution. It's the Steele dossier all over again, only more effective.
And if you don't think it will happen, you don't know political dirty tricks.
