Ok I'll try to summary:

Lula (as the figurehead of workers' party - PT) was a well know corrupt - We brazilians got used of corruptions schemes during his mandate - Like mensalão, petrolão, postalis... He has a good approval, however, because of his first mandate, Lula 1, where the economical conditions allowed him to push big social policies.

Things started to go off trails at the end of Lula 2 and Dilma 1 (his succesor) where Brazil's economy started to show the bad signs of a corrupt-ridden government and interventionism. By some miracle Dilma was re-elected but was eventually impeached in 2014 ending a 16-years PT's government. Lula (and a whole lot of politicians from all the spectre) was then arrested by a corruption scheme.

By this time, the Brazilian people started to realized that it was a conservative population giving rise to Bolsonaro, at time a federal low chambers congressman. His promises were liberalism in the economy (with a Chicago Boy as minister), pro-guns and a somewhat christian faith appeal. However, he sold himself as an Anti-PT and, for the brazilian population, this was enough.

Surely, Bolsonaro is no saint. He is insolent, truculent, curses, admires the military dictatorship of '64. There are some suspicious corruption allegations, although not near the size of the Lula's. But he at least was a moderate right-wing that actually shrinked the size of the government and facilitated gun acquisition. 

The four years of Bolsonaro were a true hell. The media beat him at any chance, they even tried to frame him as accomplice of murder of a city ​​councilor, which clearly had nothing to do with him. Then covid happened and, as Trump, he was the main responsible for the deaths.

That gave him a big disapproval rating, although he does a good portion of population that adores him, very similar to Lula's followers. The current brazilian political scenario, then, is 30% of the population that think Lula is a corrupt that shouldn't be president, 20% that think Bolsonaro is a potential coup plotter and should be arrested, and 50% that think it's a bummer to have a corrupt ex-convict to have as a president but maybe is better than Bolsonaro.

Plus, the supreme courte, especially Alexandre de Moraes, is arresting right wing supporters for saying shit and he organized the elections in a... suspicious... manner. Not in a fraudalent manner but more like: Lula can say he was innocent (he wasn't) but the (alternative) media couldn't say that Lula wasn't anti-abortion or was a convict (he was).

So Lula was elected, planning to do a radical left-wing government (not the center-left he was selling before the elections) and we have the situation we have now. 

Shit, this was way bigger than I expected and I left out 90% of the story. So yeah. Brazilian politics.

PS.: Check my flair. I'm no Bolsonarista but I do think that having a catholic pro-gun conservative president is better than having a extreme left wing president. Also, I'm not checking for grammar errors, i'm tired and stoned.

PS2.: Was wondering where the leftists were... Yes, Bolsonaro is moderate right wing, I'll call someone really a right wing when they call for extintion of the SUS (Brazilian Universal "Healthcare"). As for Lula, also yes, I will call him extreme left wing, as someone who is nationalizing industries, implementing stricter gun control and creating a "National Bureau for the Defense of Democracy", literally Ministry of Truth. I'd call moderate left wing someone who just implement social welfare system, like Bolsonaro's Auxilio Brasil (so much for him being extreme right wing).

For real tho: Brazilian politics are waay left wing, with roots on Getulio Vargas. We're 133º at the heritage economic freedom index after all.  As for the auth, as I said, the Supreme Court takes the extreme, as is arresting right wing journalists and even taking down politicians Twitters and Instagram pages. It's funny that Bolsonaro is called auth when during his government he was spineless weakling compared to the Supreme Court going way beyond the constitution limits.

Don't worry about the grammar, it was easy enough to follow, I'm glad to hear from someone who doesn't seem to have too much bias.
