I did a search on Google, and the first result for "bernie sanders paid to drop out" was from
The Onion. An article further down has Assange hinting that Sanders was threatened in some unspecified way. Nothing on the first page supported your "pretty good idea," and I'm not wasting more time on it. Conspiracy theories to suppress evidence and all I guess, but your point is that 1) you have a "pretty good idea" Sanders was paid to drop out based on what looks to be weak circumstantial evidence (and unsourced for now), 2) Gary Johnson had a gaffe that most of his followers couldn't care less about, and 3) ipso facto Gary Johnson was also paid, not to drop out but to do something so marginal and unimportant that it will make zero difference. Just think about how you got there, that a Libertarian that leans Republican would accept money to do something so trivial and dumb, that would have such little effect, when there is no evidence he's morally compromised.
Look, you're doing conspiracy theories all wrong. Go big or go home. Google secretly supporting Hillary by promoting a woman who supported women's suffrage, on some random day back in the spring? Ironclad proof they're in the bag. 45 minute video on Youtube showing how The Shining was Stanley Kubrick's apology for the fake moon landing? Gold. Vaccines secretly causing autism? JFK Jr. stuff right there! Those are sledge hammers swinging at rail road spikes. Your theory is a tack hammer on finishing nails.
