Candidate shares use valid votes. The rates for valid, blank and invalid votes use turnout. Turnout and abstention rates use eligible voters in each round. Percentage-point differences were calculated before rounding.

Turnout fell by similar amounts in both elections, with 19,092 fewer voters in 2022 and 19,220 fewer in 2026. Blank and invalid votes combined rose by 202 in 2022 and fell by 1,574 in 2026. Valid votes fell in both elections, by 19,294 and 17,646 respectively. The main difference in 2026 was how votes were divided between the finalists.

First-round voting by political camp

The categories reflect campaign and party ties. For federal and state deputies, the comparison groups PL on one side and PT, PCdoB, PV, PSOL and Rede on the other, adding votes for individual candidates and party lists. The remaining category includes candidates from other parties and alliances that span the two camps.

Political context

In 2022, Tebet and Ciro received a combined 28,952 first-round votes in Macapá and backed Lula in the second round. Jair Bolsonaro gained more votes. In 2026, Cury, Caiado, Zema and Clariana received a combined 17,567 votes and backed Flávio. Lula was the one who gained votes. Alliances provide campaign context, while the aggregate results leave open how each voter voted in the two rounds.

In Macapá, Furlan's win for governor and Lula's second-round presidential win show that results for different offices can point in different directions. Analysis by polling section could test whether Lula's gain was concentrated where Flávio lost the most votes or where turnout fell, while leaving individual voting patterns undetermined.

Testing the technical hypothesis

The literal rule discussed in the Campos study predicts Lula's gain by adding all votes for first-round candidates who were eliminated to the reduction in blank and invalid votes. Applied to Macapá, it would predict 26,735 additional votes (25,161 + 1,574), compared with 11,300 observed. The difference is 15,435 votes.

This difference follows from the accounting identity that relates turnout and votes for Flávio to Lula's net gain. The municipal comparison tests the literal prediction. Investigating a software function would require section-level evidence and controlled tests, which fall outside the scope of this analysis.

Sources and method

The study combines TSE files for the detailed count and votes by candidate and party for municipality 06050. Shares for other offices use the corresponding valid vote totals. The statewide presidential comparison aggregates all 16 municipalities in Amapá before calculating shares. Campaign alignments are based on the sources listed below.
