Illinois held its primaries on March 20. As has been well-reported, Arthur Jones, a Neo-Nazi, won the Republican nomination for U.S. House, 3rd district. Unofficial tallies show he received 16,458 votes. No one was on the ballot against him, and no one filed as a write-in.
By contrast, the last time any Republican ran for U.S. House in the 3rd district, in 2014, there were 28,883 votes cast in the Republican primary for that seat. No Republican ran in 2016.
Republican Party leaders had asked voters to leave their primary ballot blank in that race.
