The farmer can rest assured that he didn't elect Trump. All of the electoral votes in California went to Clinton. Since Trump didn't win the majority vote, the farmer's vote didn't elect Trump.
Interesting that this is in the NY Times. Also interesting that they don't mention anything about Governor Brown and the bills about making California a sanctuary state.

There are also legal actions underway to sue for the federal funds. I don't know the status of any of this, but it's interesting that it's not even mentioned in the article.
I hope that whoever was interviewing this farmer let him know that there were pending actions on both sides, unless they knew absolutely a more current status.
