The Hill has this story about candidates who were elected to the position of Election Judge via write-in votes, in the November 7, 2017 election. The article says 192 write-in candidates won for that position, in Philadelphia alone.

Pennsylvania is the only state that elects that position. Judges get paid $100 per election, and serve for four years. The article focuses on one candidate who was elected with only one write-in, his own.
