Vote trend across elections

The votes of Ronaldo Rudolfo Milbradt Trojahn 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.

City CouncillorState Dep.Mayorticket 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). From oldest (top) to newest. Click a bar to see the result of that election. The campaign finance report of each candidacy is in the list below.

Running mates and alternates do not have their own campaign account: the account is that of the main candidate's ticket.

Source: campaign finance reports filed with the TSE (open data). Radar do Voto has these data from 2006 on in general elections and from 2008 on in municipal elections; earlier campaigns do not appear. 2024: TSE data of 14/09/2026; 2022: TSE data of 13/09/2026; 2020: TSE data of 12/09/2026. Contracted spending is the total of the expenses the campaign reported; paid is the part already settled (the TSE only publishes the paid amount from 2018 on). The spending categories are the TSE's; the detail by supplier is in the dashboard. Corporate donations have been prohibited since 2015.

Candidacies

9 candidacies · elected in 2008, 2016 and 2020

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.
