In the 34-year history of USA TODAY, the Editorial Board has never taken sides in the presidential race. Instead, we’ve expressed opinions about the major issues and haven’t presumed to tell our readers, who have a variety of priorities and values, which choice is best for them. Because every presidential race is different, we revisit our no-endorsement policy every four years. We’ve never seen reason to alter our approach. Until now.

This year, the choice isn’t between two capable major party nominees who happen to have significant ideological differences. This year, one of the candidates — Republican nominee Donald Trump — is, by unanimous consensus of the Editorial Board, unfit for the presidency.
