Geoffrey Skelley, media relations person for the University of Virginia Center for Politics, has this article listing past U.S. Senate candidates who ran in the general election even after losing a U.S. Senate primary the same year. The article begins as a report on Don Blankenship of West Virginia, who lost the May 2018 Republican primary but who is petitioning to be the Constitution Party nominee. That first portion of the article has little news that hasn’t already been reported. But the latter half of the article has the history of other candidates, and that half of the article is quite valuable as a reference.
