Which propaganda technique is being used when a political candidate seems to be recalling all the good things he has done omitting facts that would justify his defeat

The propaganda used in this case is Card Stacking.

Card stacking is a propaganda technique that attempts to emphasize the good sides of the work of politicians and neglects the bad sides. In this way manipulation of voters is done. Such an emphasis can be achieved through the bias of the media or the use of unilateral testimony or simply by censoring the critics' votes.

The propaganda technique of Card-Stacking is so widespread that we can not always be aware of his presence. Basically, Card-Stacking means card-sharing for the benefit of politicians, which has no connection to the actual situation.

I give an example of this propaganda in advertising the product. If a particular product is filled with sugar (and calories), the advertisement can emphasize that there is little fat in the product, which means that there are few calories. This does not, of course, increase the quality of the product, but people get the impression that this is the case.
