negative campaigning?

[Adonay Felipe Nogueira]

Indeed, he has a point. This can be associated with a losing party by
some people.

However, since I don't know if he considers "negative campaigns" as
"those saying things without facts and references being exposed" or if
he considers "negative campaigns" as "those merely based on insults". I
would consider the first case to be signalling a losing party. However,
the second case for me is mainly used by a losing party.
