From Jonathan Chait on New York magazine's website:

Amazingly, even as Democrats painted Trump as an authoritarian menace, he continued to confirm the point on the ground. Weeks earlier, Trump's campaign had banned the Washington Post, whose coverage it found objectionable, from campaign events. The ban had only symbolic meaning, though. ... But yesterday, the Trump campaign extended its ban from the symbolic to the real by preventing Post reporter Jose DelReal from entering a public speech by Trump's vice-presidential nominee, Mike Pence. Private security first told DelReal he could not enter the rally with his laptop and phone. DelReal asked if other attendees were allowed to bring phones and was told, “Not if they work for the Washington Post.” DelReal placed the items in his car, returned, was patted down by security, and then still told he could not enter. Later, Pence's staffers insisted it had all been a mistake, blaming overzealous local staffers. This sort of iterative, inconsistent, and even chaotic sequence of events fits a common pattern of how political authoritarians break down rules and norms.

Be afraid. Or better: Keep Calm and Fucking Vote.
