Agreed! Brazil has a very complex federal quasi-presidential system!

Please please please read academic books about the political history of Brazil or contemporary politics in Brazil instead of listening to a rando like me on the internet!

I'd recommend reading "Modern Brazil: A Social History", "The Brazilian Constitution of 1988: a comparative appraisal", "Constitutional Engineering in Brazil: The Politics of Federalism and Decentralization", etc, but there are some additional papers and books I could recommend as well.
