I'm confuse, since Brazil is a republic, does it have a congress and how many are in congress?

I tried to answer your question and came across this: 

[quote]From 1889 to 1930, the government was a constitutional democracy, but democracy was nominal.

In reality, the elections were rigged, voters in rural areas were pressured or induce to vote for the chosen candidates of their bosses (see coronelismo) and, if all those methods did not work, the election results could still be changed by one sided decisions of Congress's verification of powers commission (election authorities in the República Velha were not independent from the executive and the Legislature, dominated by the ruling oligarchs). This system resulted in the presidency of Brazil alternating between the oligarchies of the dominant states of São Paulo and Minas Gerais. This regime is often referred to as "café com leite", 'coffee with milk', after the respective agricultural products of the two states.[/quote]

You're a republic/democracy, but only by name. You should do some serious reforming to get rid of this corruption.
