Brazil is a federal republic with 26 states and a federal district. The 1988 constitution grants broad powers to the federal government, made up of executive, legislative, and judicial branches. The president holds office for 4 years, with the right to re-election for an additional 4-year term, and appoints his own cabinet. There are 81 senators, three for each state and the Federal District, and 513 deputies. Each state is eligible for a minimum of 8 seats; the largest state delegation (Sao Paulo's) is capped at 70 seats. This system is weighted in favor of geographically large but sparsely populated states.
Luiz Inacio Lula da Silva is the current president; he was re-elected with 61% of votes in 2006.
