Video of the Trump appearance is available from Reuters, among many other sources. It appears to us far likelier that the similarity between the candidate’s gesticulations and the reporter’s infirmity was mockery than pure coincidence.

To judge from our Twitter feed, which includes a good number of conservative journalists, that’s the media consensus across ideological lines. One suspects that, as has often happened before, Trump’s supporters will see the matter differently. Which brings us to the Trump paradox: How can his supporters and his detractors see the same behavior in such drastically different lights?

We noted another example on Tuesday. Trump’s account of having witnessed thousands of Muslims celebrating 9/11 in New Jersey appears to be inaccurate, whether an honest error of recollection or a deliberate deception. But it challenges the official lie that, as told by Hillary Clinton, Muslims “have nothing whatsoever to do with terrorism.” Thus Trump’s supporters see him as a truth-teller even when he isn’t telling the truth.
