How a conspiracy gets started

I had a dream last night and it appeared quite vivid.  Hillary Clinton's team, I had read in my dream, was in crisis talks as the polls tightened and there was a fair old bit of panic.  Just before going to bed, I had observed on the 538 statistical analysis website that Trump was now a whisker of a percentage point ahead in North Carolina and Florida and Nevada was a dead heat.  Obviously this influenced my dream as I pondered in my unconscious how politicaal candidates can keep smiling as their ambitions crash and burn.
Now, it is true that Clinton is but a statistical polling error away from defeat to Trump and in the last two weeks the election has become about her rather than her opponent, to her detriment.  But I now see how conspiracy theories against the politicians people want to hate spring up.  I have no particular axe to grind against Clinton - in fact, no-one has ever been more prepared to become president (and in Donald Trump, least prepared - part of his attraction).  If Trump wins, I will be despondent and just hope Congress can keep him from being too egregious until 2021.
However, if was motiviated to do so, I could go on a site like 4Chan (which - like Trump - describes itself as 'politically incorrect' in trying to make mainstream its racism, misogyny and anti-semitism) and, without any evidence, say the Clinton camp was in crisis, gripped with panic.  It felt pretty real in my dream, so it must be pretty real in reality.  Then this spreads within the silo for the Republican-inclined and helps shore up the anti-Clinton vote for the GOP. 
And this is how conspiracy theorists like Alex Jones on InfoWars sustain their worldview - their wacko ideas seem quite likely to them and so they must almost certainly be true.  Evidence, pfft!  We'll cherrypick from here and there, make a leap of the imagination and, hey presto, it's suddenly a fact.  Maybe even the despised mainstream media will pick up on it and press those in the 'establishment' about it.
The things put out about Clinton are ludicrous (Trump only comes under attack when he shoots himself in the foot) and one can understand her misjudged comment about half of Trump's support being a basket of deplorables.  In the 1990s, she talked about a vast right-wing conspiracy attacking her husband.  It may have been true - it felt true but that doesn't mean it was.  Now conspiracies are coming back to haunt her and may even cost her the election.
