Vote trend across elections

46,638 votes in 2026 (elected) · 10 elections

The votes of Themistocles de Sampaio Pereira Filho in each election they ran in, from oldest to most recent. All on the same scale (the highest vote recorded); the color shows the office.

State Dep.Governorticket votes (running mate/alternate)

The longest bar (the one that goes all the way) is the highest vote recorded for any office, elected or not; it works as a ruler, and all the other bars are proportional to it (the longer the bar, the more votes). What shows whether the person was elected is the fill, not the length: filled (colored) bar = elected; only the dashed outline = not elected; "to the runoff" = went to the runoff. The hatched bar marks an executive running mate or an alternate senator: they do not receive individual votes, so the bar shows the ticket votes of the main candidate (hence the "ticket" next to the number).

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.
