Perhaps it was the man’s strong but plain-spoken rebuke outside a Roy Moore rally on the campaign’s final night, condemning the candidate’s past comments lambasting homosexuality.

Perhaps it was the admission of the man, a peanut farmer, that he too, had harbored some of the same anti-gay feelings.

Perhaps it was his sign, a photograph of his daughter, a lesbian who, he said, had killed herself when she was 23.

Whatever it was, the two-minute video of Nathan Mathis, 74, who spoke outside the Republican candidate’s rally, struck a nerve, traveling far and wide as a sort of emotional coda to a wrenching U.S. Senate race in Alabama that has captivated the country. Alabama voters will go to the polls on Tuesday to choose between Doug Jones, a moderate Democrat who came to prominence helping to prosecute Ku Klux Klan members as a U.S. attorney in the 1990s, and Roy Moore, a far-right conservative and former judge whose candidacy has sharply divided the party he represents and the electorate beyond.

You can watch Mathis talking to reporters, below. So far the tweet has received over 2 million views, over 30 thousand retweets and thousands of comments.
