[2] Gevald campaigns are typically a last-minute affair run on or in the lead-up to election day.
Tactics used during Gevald campaigns often include spreading messages warning of the catastrophe that would supposedly occur if voters would not vote for the "correct" option.
Typically, these messages would paint the picture of an impending economic or socio-political disaster, and include terms with negative connotations such as "danger" and "crisis", meant to increase fear and panic amongst the voters.
The purpose of this scaremongering is to "guide" potential voters into believing that voting for an option not supported by the campaign would result in misfortune.
