This person's history at the polls, from the most recent candidacy to the oldest.

G é Eleição Geral: presidente, governador, senador e deputados. L é Eleição Local (municipal): prefeito e vereador. De 1933 a 1990 o TSE não publica cargo municipal, então esses anos são todos G.

A candidacy without votes is a registration that did not reach the ballot: according to the TSE data, a registration not approved, a withdrawal, or a running mate, who does not receive individual votes.

The race or color is the one the person declared to the TSE in the registration of each candidacy. The Court started collecting this information in 2014; that is why it does not appear in earlier candidacies.
