Over half the states in which major party gubernatorial and U.S. Senate candidates have debated each other have included at least one minor party or independent candidate in those debates. However, this year in California, no statewide candidate debates between the major party nominees have included any minor party or independent candidates.
On October 6, the California minor party gubernatorial candidates held a press conference in Sacramento, to publicize the idea that California is behind the remainder of the country. The event was sponsored by Free & Equal. See this Sacramento Bee story.
The November 1 print edition of Ballot Access News will list the states and debates that have been inclusive, for statewide office.
