Some scandals become scandals in the absence of any evidence proving wrongdoing, because partisan foes labelled them that way. They’re still scandals, in our eyes, going by the definition of “disgraceful gossip about the private lives of other people” or “conduct that causes or encourages a lapse of faith.”

Sir John A’s government was taken down by The Pacific Scandal. There are 9 others listed that occurred in the 20th century.
Interesting that politics is an equal opportunity scandal maker. It’s about people who become politicans doing inappropriate or illegal things, regardless of party affiliation. We have a colourful history.
