"Symbolism" refers to the use of certain symbols in order to represent a particular idea. This means that the symbols look different from how they literally mean.
For example, the "OK" hand gestures, which may seem innocent are now considered part of the "hate list symbols." This is actually a controversial issue which may seem to have started as a joke but actually carries a deeper meaning.
When it comes to election, the electoral symbols are being used in a political party's campaign. These allow illiterate voters (specifically, those who cannot read and write) to know which candidate they want to vote.
