Usually when someone loses a presidential race, they kinda disappear for a while. Lay low. Rebuild themselves. For example, Al Gore took his time to make an inconvenient truth. But that was 6 years later.
In contrast, Hillary just refused to leave, with her book about what happened and such. Some of the crazy last minute allegations disappeared like the kid claiming trump rape, but the russian meddling allegation dragged on very long.
Of course it allows media corporations to pressure a president, as it's harder to do certain things when there's 24/7 narrative to undermine.
There's always been some pressure to get your own side to comply, but I think Hillary's obvious corruption and inability to hide it, really accelerated things. Though I suppose the Bush florida recount could compare. But even that wasn't dragged on THIS long. I don't think there's been such a push to get people to unfriend wrong-thinkers, I guess the closest thing is the mccarthyist red scare. Because of the obvious corruption, both in cheating Bernie and the forceful attempts to instill loyalty and support, it's hard to turn off that reign of fear the moment the election is over.
