For many listeners, nothing was worse than Hillary Clinton. Two decades of vilification had taken their toll: Listeners whom I knew to be decent, thoughtful individuals began forwarding stories with conspiracy theories about President Obama and Mrs. Clinton — that he was a secret Muslim, that she ran a child sex ring out of a pizza parlor. When I tried to point out that such stories were demonstrably false, they generally refused to accept evidence that came from outside their bubble. The echo chamber had morphed into a full-blown alternate reality silo of conspiracy theories, fake news and propaganda.
And this is where it became painful. Even among Republicans who had no illusions about Mr. Trump’s character or judgment, the demands of that tribal loyalty took precedence. To resist was an act of betrayal.
