>Then in 2016 we saw massive Bernie Sanders support to a swift and sudden change to Hillary Clinton support. That was followed by the "Correct the Record" movement and then later "Share Blue." These were all coordinated efforts to inorganically promote one political party and suppress another.
I see this claim often, and having been a Reddit user from back when there no comments and no subreddits, I can tell you what you're claiming is not remotely the most plausible option.
Right from the beginning Reddit swings left wing and libertarian, their first preference is someone like Ron Paul and Sanders. That's why you see competing candidates demonized, and those candidates idolized. They don't like the mainstream GOP at all.
The sudden swift that you're talking about happened it was clear that Sanders would lose the primaries and after he conceded the race, and told his supporters to support Clinton. Reddit didn't like Clinton in 2008 and in 2016, but they would take her any day over Trump or any other GOP candidate except Ron Paul.
Why would you expect Reddit to keep supporting Sanders after he conceded the race? Who would that help? That would help Trump. That's why a lot of right wingers including Russian trolls encouraged making Sanders supporters angry to suppress turnout. That's why you saw the massive shift after the primary because that sub on Reddit does not like Trump at all and would even have Clinton over Trump. Think of the typical Sanders or Warren supporter, would they support Trump or Clinton as President?
All these complaints about Shareblue and CTR are just noise, and what T_D and conspiracy subs convinced a bunch of people was happening.
Why couldn't CTR or Shareblue suppress Sanders support and chime up Clinton support on Reddit before Sanders gave up? The Sanders sub was regularly multiple times in r/all and Clinton support and subs weren't popular at all even in r/politics. If they were so powerful, why can't SB or CTR suppress Sanders support over the past few months when he has become a viable candidate?
No one can give a straight answer, because there isn't one, yet they are absolutely convinced of their version of events. It's the modern day version of an urban legend given how many people believe in the narrative you posted.
