Since a recent political history of Brazil is one of the subjects of my interest, I wonder if there's anyone else to discuss possible mini-what if scenarios like:
1. Kubitschek is prevented, as there were some concerns about such a possibility, from taking office in 1955.
2. Quadors did not resigned in 1961.
3. Goulart is allowed to complete his term, no 1964 coup.
4. Neves haven't fall sick in an even of his inauguration in 1985. Thus no Sarney Presidency.
5. In 1993, with a stunning upset, Brazilian voters backs restoration of the constitutional monarchy, with giving effective power to the Prime Minister (please remember party loyalty in Congress was weak at this time and building a majority was very difficult task).
6. Due to the constututional changes Itamar Franco is allowed to and did run for a full term in 1994 (and he had +80 approvals)
7. Fernando Henrique Cardoso is not allowed to run for reelection in 1998, due to retaining one term limit.
