Tom Metzger won the Democratic primary for California's 43rd Congressional district with a little more than a third of the votes cast. Many credited his win to his ballot description as a "small business owner." A more accurate description was "Grand Wizard, Ku Klux Klan."
In 2018, proud American Nazi Arthur Jones was unanimously nominated as the Republican candidate for the Illinois 3rd Congressional district.
The Illinois Republican Party has denounced Jones and has said they want some Republican to run a write-in campaign. It is likely no one will. No Republican ran against him in the primary or signed up as a third party candidate because no one wanted to taint their Trumpian creds by opposing a white nationalist.
In 1980, the Democratic Party was quick to denounce Metzger and endorsed the Republican, Clair Burgener, in the general election. With the support of both parties, Burgener won a resounding victory.
What Illinois Republicans have steadfastly refused to do is endorse Jones' Democratic opponent, Dan Lipinski. In the end, the Republican Party will weakly embrace their Jew hating, Holocaust denying candidate because "the worst Republican is better than any Democrat."
Update: Ten Cruz has called for Republicans to vote for Democrat Lipinski. So far, he is the only Republican in the country to take that stand.
Update 2: Fulfilling my prediction, Republican governor Bruce Rauner adamantly refuses to endorse the Democrat even when the Republican candidate is an open Nazi.
