# Brazilian electoral campaigns and 2026 election outlook > Live situation record from CLSTR: https://clstr.news/situations/brazilian-electoral-campaign-and-funding-disputes > Updated: 2026-09-04T20:20:08.000Z. Sources: 85. Developments: 7. The Brazilian electoral landscape is being shaped by political alliances, disputes over the distribution of the Electoral Fund, and preparations for the 2026 elections. In the state of Acre, municipal leaders are playing a decisive role by aligning with gubernatorial candidates. A survey by Ascema Nacional identified 11 candidates in Acre linked to approximately R$ 9.9 million in environmental fines; notably, state deputy candidate Zé Lopes holds the largest individual fine, exceeding R$ 8.1 million. As the 2026 cycle intensifies, Senate races are gaining momentum. The upcoming elections will involve contesting two Senate seats in each state and the Federal District, a process that will renew two-thirds of the 81-member Senate. In Rio Grande do Sul, the Superior Electoral Court (TSE) has officialized 13 Senate candidacies. Resource allocation remains a central point of contention, with public funds driving 93% of the R$ 3.38 billion in declared resources for the 2026 elections. New trends in candidate demographics show a significant increase in neurodiversity representation; according to TSE data, the number of candidates identifying as autistic rose from 13 in 2022 to 70 in 2026. In Ceará, the gubernatorial race shows Ciro Gomes maintaining a lead over Elmano de Freitas, though the margin varies between 2.6 and 11 percentage points. High concentrations of undecided voters in Minas Gerais, São Paulo, Rio de Janeiro, Espírito Santo, and Rio Grande do Sul are considered decisive for the presidential succession. In Rio Grande do Sul, undecided voters reach 18%, while Minas Gerais and Espírito Santo stand at 17%. These undecided voters could represent approximately 8.9 million votes, a figure that significantly exceeds the margin of victory in the previous presidential election. ## Claims - Indigenous candidates increased from 50 in 2022 to 75 in 2026.
