These are smart, rational people falling for a scam. Why? It’s in part because Twitter fosters this group-think and lack of critical thought — you just click a button and, with little effort, you’ve spread whatever you want people to believe — but it’s also because they’re so convinced of the righteousness of their cause (electing Clinton/defeating Trump) that they have cast all limits and constraints to the side, believing that any narrative or accusation or smear, no matter how false or conspiratorial, is justified in pursuit of it.

But while Donald Trump’s candidacy poses grave dangers, so does group-think righteousness, particularly when it engulfs those with the greatest influence. The problem is that none of this is going to vanish after the election. This election-year machine that has been constructed based on elite unity in support of Clinton — casually dismissing inconvenient facts as fraudulent to make them disappear, branding critics and adversaries as tools or agents of an Enemy Power bent on destroying America — is a powerful one. As is seen here, it is capable of implanting any narrative, no matter how false; demonizing any critic, no matter how baseless; and riling up people to believe they’re under attack.
