In May 2018, it was revealed that an error by local election officials caused 26 voters to cast ballots in the 93rd district when should have cast them in the district that Yancey won. Records indicate that 17 of the 26 voters were likely to vote Democratic because they had previously voted in Democratic primaries while only one voter had voted in a Republican primary. Since the 2017 election was decided by such narrow margins, the 26 misaligned votes may have cost Democrats the seat and thus majority control in the Virginia House.
